Amazon.com Product Description
Wherever your hectic schedule takes you, you'll stay productive thanks to reliable HP Compaq Presario C727US notebook PC, which offers all the basics at a nicely affordable price. This 6.4-pound laptop is powered by the powerful 1.46 GHz Intel Pentium T2310 dual-core processor and features 54g wireless networking (802.11b/g), enabling you to stay connected at coffee shop and airport hotspots. Its 15.4-inch WXGA BrightView display supports High-Definition playback enhanced by Altec Lansing audio.

You can easily burn your home video productions to DVD for friends and family with the dual-layer, multi-format DVD/CD burner, which enables you to store up to 8.5 GB of data on a DL disc. Create custom laser-etched disc labels right in the drive with LightScribe and preinstalled Roxio ExpressLabeler. Other features include a 120 GB hard drive, 1 GB of installed RAM (maximum capacity), and Intel GMA X3100 video processor with up to 251 MB of shared video RAM.

This laptop also comes preinstalled with Microsoft Windows Vista Home Basic, which delivers a safer, more reliable, and more productive computing environment. It integrates new search tools throughout the operating system, includes new parental control features, and offers new tools that can warn you of impending hardware failures.

The Basics

  • Processor: The 1.46 GHz Intel Pentium T2310 dual-core processor delivers additional computing resources and help expand the PC's capabilities by providing higher throughput and simultaneous computing. You'll be able to perform multiple tasks such as digital rendering and gaming all while running virus scan or other background tasks seamlessly. Each core shares 1 MB of L2 cache, and they have a 533 MHz front-side bus. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

  • Hard Drive: The 120 GB hard drive (5400 RPM) offers enough to room to hold a digital audio library of over 20,000 songs and still have room left over for movies, games, and a large collection of software. This Serial ATA (SATA) hard drive also quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0.

  • Memory: This notebook comes with 1 GB of installed RAM, which is also the maximum capacity for this notebook. With this amount of memory, you'll be able to easily work on documents and spreadsheets as well as manage a digital audio and video library, but it's underpowered for 3-D gaming and video editing.

  • DVD/CD Drive: This multiformat DVD/CD drive is compatible with writing both DVD+ and DVD- disc formats as well as dual-layer (DL) DVD+/-R discs, which can store up to 8.5 GB of data. It features 4x DVD-R DL Write Once, 2.4x DVD+R DL Write Once, 8x DVD+R, 4x DVD+RW, 8x DVD-R, 4x DVD-RW, 16x DVD-ROM, 40x CD-R, 24x CD-RW, and 40x CD-ROM speeds.

    This LightScribe DVD+/-RW drive lets you laser-etch silkscreen quality text and images on to CDs and DVDs . Your software, PC and discs work together for a no-hassle way to burn just the labels you want. After you burn content, just flip the disc over, reinsert and burn your label--anything from a simple title to a full-disc work of art.

  • Keyboard & Mouse: This notebook has a 101-key keyboard and a touchpad with on/off button and dedicated vertical/horizontal Scroll Up/Down pad.
Screen, Video & Audio
You'll enjoy razor-sharp graphics and widescreen movies with the 15.4-inch WXGA high-definition screen, which displays an 18 percent larger picture than standard 15-inch screens and offers up to an 18 percent improvement in contrast ratio. It has a widescreen resolution of 1280 x 800 pixels--perfect for watching DVD movies the way they were meant to be seen. Video is powered by the Intel Graphics Media Accelerator X3100, which uses shared video memory (up to 251 MB allocated from the system memory) and provides Windows Vista Aero interface support and enhanced 3-D graphics performance--delivering over 2x scores on 3-DMark 06. Intel Clear Video Technology provides outstanding video playback with sharper image quality, increased clarity, and customizable color controls. It also enables enhanced visual quality of interlaced content on progressive displays.

The Altec Lansing speakers provide exceptional sound, and a pair of stereo earbud headphones with volume controls is included. You'll be able to privately share enjoyment of multimedia with a friend via the dual headphone jacks.

Networking, Connectivity & Expansion

  • 1 headphone jack and 1 microphone jack
It also has an integrated 56K modem (V.90) and an RJ-45 LAN network port (for a 10/100 Ethernet connection to networks and DSL/cable modems).

Operating System

You can also use Windows Media Center to record and watch your favorite TV shows (even HDTV) and to access new kinds of online entertainment content. Computers that include Windows Vista Home Premium and an auxiliary Windows SideShow display will also allow you to access key data even when your computer is off.

Great laptop, vista just sucks5
I have had this laptop for a while now and I can do anything on it. I might have to adjust a little bit here and there but when you get to know how to use vista, this laptop becomes all you need. Lots of hard drive space. Fast processor. Built in wireless and 3 usb ports. The only thing I would change is the battery. Mine is horrible but there is a chance the abuse I have given it is the problem and not the battery itself.

This is singlehandedly the WORST product I have ever purchased1
Actually, it's the worst product my boyfriend ever purchased because he bought it for me for Christmas last year. This thing never worked right, tech support was horrendous, we sent it back to HP twice to get it fixed and they never solved the problem. I took it into an independent shop to get it diagnosed and there's a crack on the motherboard, which makes the laptop not worth fixing at this point. I've finally come to terms with the fact that this computer is a lemon. Shame on HP for not making it right. I will never purchase anything from them ever again.

Good for the price3
This was given to me as a gift, wasn't what I asked for, but anyway. Mine died after owning it for 1 month. Basically it was problem with Vista. I chatted with the HP tech online on another computer trying to fix the problem, no dice. The technician claimed it was my fault I broke it. Oh, I did not get a recovery disk when I got the laptop either, so it didn't help the situation that I had to wait 1 month for the recovery disk while HP sent it to me. Yes, mine was a faulty programming issue by Vista as I later determined. I had asked for a much tougher laptop because I do digital photography. But because this one only has 1GB RAM, when I use photoshop, all the other programs has to be shut down. By the way, the laptop came with 1 year of anti-virus and X number of Office use. But since mine had to be rebooted, I lost all that. I no longer have 1 year free use of anti-virus or the X-number use of Office. Just a word of warning to people who is getting this. But considering the price, not a bad deal if you just need something that you can haul around with you on the go. If yours do break and you can actually get someone from HP who knows anything about Vista to chat with you, then you will be ok. I had to call HP 3 times to get someone who actually knew what I was talking about. And the person knew instantly it was faulty programming by Vista, which caused my laptop to completely freeze and wouldn't turn on anymore.

Amazon.com Product Description
Built for today's multimedia-savvy, always on-the-go computer user, the HP Pavilion dv2890nr Artist Edition takes its award-winning imprint designs to the next level with a unique artistic rendering wrapped around the entire laptop. HP's Take Action/Make Art contest received over 8,500 entries from aspiring young artists worldwide, and this bold, colorful, innovative design stood out at capturing the HP PC experience. You can also travel in style with the coordinating Artist Edition messenger bag (sold separately).



Show your individuality with the Artist Edition HP Imprint finish, featuring the winning design from a worldwide competition sponsored by HP and MTV.


More than a pretty face, the dv2890nr Artist Edition PC delivers rich digital entertainment and excellent mobile performance.
Optimize your mobility with a BrightView 14.1-inch display that has the same viewable area as a 15.4-inch screen--in a notebook that weighs a pound less. Encouraging more direct interaction, the backlit media control panel responds to the touch or sweep of a finger. Control settings for audio and video playback from up to 10 feet away with the included HP remote, then store it conveniently in the PC card slot. Enjoy movies or music in seconds with the external DVD or music buttons to launch HP QuickPlay (which bypasses the boot process).

It's powered by the 1.83 GHz Intel Core 2 Duo T5550 processor, which provides an optimized, multithreaded architecture for improved gaming and multitasking performance, as well as excellent battery management. It also includes Intel's 4965 AGN wireless LAN, which will connect to draft 802.11n routers and offers compatibility with 802.11a/b/g networks as well. It also features a 250 GB hard drive, 3 GB of installed RAM (4 GB maximum), LighScribe dual-layer DVD±R burner, HDMI port for connecting to an HDTV, and Nvidia GeForce Go 8400M GS video/graphics card with up to 1407 MB of total allocated video memory (128 MB dedicated). It also includes an integrated Webcam in the LCD's bezel and an omnidirectional microphone for easy video chats.

It comes preinstalled with Microsoft Windows Vista Home Premium (Service Pack 1), which includes all of the Windows Media Center capabilities for turning your PC into an all-in-one home entertainment center. In addition to easily playing your DVD movies and managing your digital audio library, you'll be able to record and watch your favorite TV shows (even HDTV). Vista also integrates new search tools throughout the operating system, includes new parental control features, and offers new tools that can warn you of impending hardware failures.

Make a Statement with the HP Artist Edition Notebook PC
Winning the international Take Action, Make Art competition co-sponsored by HP and MTV was João Oliveira, a 20-year-old artist from Portugal, who combined retro sensibility with modern technology and a unifying Asian theme. Oliveira's design is found both inside and out on this Artist Edition laptop, and his art also appears in coordinating wallpaper options, product packaging, and documentation. HP's high-gloss Imprint finish encases the elegant, curvilinear form and is more durable than traditional painted surfaces.

The Basics

  • Processor: The Intel Core 2 Duo T5550 processor has a 1.83 GHz processor speed, fast 667 MHz front-side bus (FSB), and 2 MB L2 cache. (An L2, or secondary, cache temporarily stores data; and a larger L2 cache can help speed up your system's performance. The FSB carries data between the CPU and RAM, and a faster front-side bus will deliver better overall performance.)

    With two computational execution cores in a single processor, it provides greater system response when running multi-threaded applications simultaneously with no significant increase in power consumption. It's optimized for multitasking and is ready to support the Microsoft Windows Vista operating system. It can simultaneously run multiple demanding applications--such as graphics-intensive games or serious number-crunching business productivity applications--while downloading music or running virus-scanning security programs in the background. Some of the advanced Intel innovations of the Core 2 Duo processor include:

    • Smart Memory Access: Improves system performance by hiding memory latency, thus optimizing the use of available computer data bandwidth to provide data to the processor when and where it is needed.
    • AdvancedDigital Media Boost: Effectively doubles the execution speed for instructions used widely in multimedia and graphics applications.
    • Dynamic Power Coordination: Coordinates Enhanced Intel SpeedStep Technology and idle power-management state (C-states) transitions independently per core to help save power.
    • Deeper Sleep with Dynamic Cache Sizing: Saves power by flushing cache data to system memory during periods of inactivity to lower CPU voltage.

  • Hard Drive: The 250 GB Serial ATA hard drive is more than double the average size for notebook PCs, and it offers a fast 5400 RPM disk speed--an improvement over other notebooks with extra-large hard drives. It provides more than enough capacity for storing documents, digital media files, and video editing software. This SATA hard drive also quickens the pace with a higher speed transfer of data--akin to FireWire and USB 2.0.

  • Memory: This notebook comes installed with 3 GB of RAM (DDR2), which helps boost the amount of available video RAM that's shared with this notebook's video card. It has a 4 GB RAM capacity.

  • DVD/CD Drive: This multiformat DVD/CD drive is compatible with writing both DVD+ and DVD- disc formats as well as dual-layer (DL) DVD+/-R discs, which can store up to 8.5 GB of data. It features 4x DVD-R DL Write Once, 2.4x DVD+R DL Write Once, 8x DVD+R, 4x DVD+RW, 8x DVD-R, 4x DVD-RW, 16x DVD-ROM, 40x CD-R, 24x CD-RW, and 40x CD-ROM speeds.

    This LightScribe DVD±RW drive lets you laser-etch silkscreen quality text and images on to CDs and DVDs . Your software, PC and discs work together for a no-hassle way to burn just the labels you want. After you burn content, just flip the disc over, reinsert and burn your label--anything from a simple title to a full-disc work of art.

  • Keyboard & Mouse: This notebook has a 101-key keyboard and a touchpad with on/off button and dedicated vertical/horizontal Scroll Up/Down pad. It also includes two quick-launch buttons (HP QuickPlay Music and DVD).
Screen, Video & Audio
While this notebook is actually as wide as standard 15-inch displays, the high-definition, widescreen 14.1-inch display (1280 x 800-pixel resolution) has the same form factor as a 12-inch screen--taking up less space on your desk. Video is powered by the Nvidia GeForce 8400M GS graphics card, which provides up to 1407 MB of available RAM/video memory (128 MB dedicated video RAM) for unmatched HD video performance on a notebook PC. With support for Microsoft DirectX 10 Shader Model 4.0 and High Dynamic-Range Lighting (HDR), the 8400M lets you rip through all of today's most advanced and cutting-edge games and applications.

The Altec Lansing speakers provide exceptional sound, and a pair of stereo earbud headphones with volume controls is included. You'll be able to privately share enjoyment of multimedia with a friend via the dual headphone jacks.

Networking, Connectivity & Expansion
Be ready for the next platform in wireless connectivity with this notebook's integrated quad-mode Wi-Fi chip. Based on the draft 802.11n Wi-Fi specification, it offers up to five times the performance and twice the wireless range as existing 802.11g wireless. It's also backward compatible with 802.11b/g networks (commonly found in home routers and Wi-Fi hotspots) as well as 802.11a networks (which has a higher throughput, but more limited range--great for closed office environments).

It also includes a next-generation ExpressCard 54/34 card slot (as well as a standard PCMCIA slot), which lets you take advantage of thinner, faster, and lighter expansion cards for even more advanced wireless, networking, storage, and security features. Here's the full list of connectivity options:

  • 2 USB 2.0 ports for connecting a wide range of peripherals--from digital cameras to MP3 players
  • 1 FireWire (also known as IEEE 1394 or i.Link) port for connecting digital video camcorders and other peripherals
  • 1 HDMI output (for connecting to a compatible HDTV or home theater receiver for uncompressed digital audio and video via a single cable)
  • Analog video out: 1 VGA monitor port and 1 S-Video port for connecting to a TV or projector
  • 1 ExpressCard/54 slot (also supports ExpressCard/34)
  • 2 headphone jacks
  • 1 microphone jack
  • 1 Expansion Port 3 connector (for use with the HP xb3000 Expansion Base or the HP Notebook QuickDock)
  • 1 IR receiver
  • 5-in-1 memory card reader (Secure Digital, MultiMedia, Memory Stick, Memory Stick PRO, xD Picture Card)
  • 10/100 Ethernet
  • Bluetooth
  • 56K modem (V.90)

Operating System
This PC is preloaded with Windows Vista Home Premium Service Pack 1 (SP1), which collects previously released updates for Windows Vista for improved security, reliability, and performance. It also provides support for emerging hardware and standards, such as an Extensible Firmware Interface (EFI) and flash-based devices formatted using the Extended File Allocation Table (exFAT) file format, and adds improvements that will help businesses better optimize their IT infrastructures.

Windows Vista Home Premium is the operating system for users with advanced computer needs, and it includes all of the Windows Media Center capabilities for turning your PC into an all-in-one home entertainment center for watching DVD movies and accessing your digital audio library.

Writing my review from this computer!5
Ok I just love my artist edition HP, I used to own a black regular dv2000 and I had a lot of problems with that one, I had to sent it for repair and everything and, I don't know.. overall I didn't have a good experience with that one...
But I traded my old one with my dad and bought this artist edition just crossing my fingers hoping this one to be a keeper, and IT DEFINITLY IS!
No webcam problems (other one worked 1/3 times I tried using it), the touch buttons are more resposive, the touchpad buttons feel more rigid...
And the desing on the computer makes it unique!
So its fully recommended!

Great laptop and service from Amazon4
I ordered this laptop with 2 day delivery and the delivery was right on time before I had to be out of town and wanted to take the computer with me. I have an HP Pavillion Media Center Desk Top for almost 2 years and have been very happy with it, so it made sense to order another HP when I was searching for a laptop. This laptop was by far the easiest computer to get set up and learn all the new features that I was not familiar with. I also like the Artist version, which stands out when I am out with the laptop -- no chance of someone mistaking it for their's! I am very pleased with my HP laptop, as well as Amazon.com's service. The only reason I am not giving it a 5 star is that the system is a bit slow to boot up -- but from that point on, it works very well.

This is an excellent notebook with very good especifications.

How To Become A Video Game Programmer

Author: Tom Bak
For many, working as a video game programmer at a famous development studio sounds like a dream job. You get to design and build fun new games all day. Here are some tips for making this dream a reality.Know what you're getting intoBefore you dive into becoming a video game programmer, spend a little time to research what working at a video game studio actually entails. You don't want to spend time and effort becoming a video game programmer only to realize that it's not what you were hoping for. Working as a video game programmer takes a lot of effort. The work hours and deadlines can get stressful, especially near the end of a project. Talk with people who are in the video game business, either in person or online, about any questions you may have about the business.Create your own gamesTry your hand at making your own games at home to see what it's like. You can start with simple projects first, such as basic text games or simple shooters. Grab a book on video game programming at your local bookstore (there are many to choose from) and dive in. C and Java are good programming languages to start out with. Don't try to create something too big or you'll quickly get overwhelmed. The purpose of this is to learn what it's like to make games and get a little experience, not to develop the next award winning MMORPG. Development studios will be more likely to hire you if you have a good project or two that you can include with your resume.Go To CollegeCurrently video game development studios are hungry for programmers. They spend a lot of money using headhunters to help them locate new people to hire. The good news is that once you are in the video game business, there are many opportunities for companies to work for. There are many different projects and locations that you can choose from. The bad news is that the studios can be very picky about hiring new employees with no previous video game programming experience. Therefore it can be very hard to get your foot in the door. Going to college for a Computer Science degree and getting excellent grades is one of the best ways to show video game studios that you will be a competent and committed employee. The classes will also give you many of the skills that you need to work. There are schools now that specialize in video game degrees, such as DigiPen. They are still relatively new and it's not clear whether they increase your chances of getting a job in the video game industry.Play GamesKnow your games! The video game industry is changing at a breakneck pace, so it's important to stay up to date with the new products. Play many different games every month to see what companies are doing now with video games. Development studios want to make sure that they only hire programmers that are devoted to video games. Staying up to date with videogames is an excellent way to demonstrate this.Good luck!

Pen Drive - A Necessary Evil?

Author: Roberto Sedycias
Technology has always been a necessary evil. The more the technology develops, the greater are the chances of its being abused. Pen drive, the small storage device used to store and transfer data to and from computers, has gained popularity due to its functionality. It has got thousands of uses. Ease of use and convenience is the prime reason of its popularity.However, like many other equipments, pen drives are also a necessary evil and pose a potential security threat to the technology world. When placed in wrong hands, the portability and high storage capacity of the pen drive can be hazardous. The device has evolved as a threat to the corporate and other organizations where security of data is given utmost importance.The threats that are associated with pen drives are serious. Some of them are listed below.Stealing of data:Apart from the defense department, the corporate sectors all over the world are under the threat of data theft for espionage. There is no dearth of incidents where spies, hackers and other source are employed to steal data. A pen drive gives ample of opportunity for the theft from an unattached or unlocked PC with a USB port. It is easy to access data and steal information like client list, research data or any other information. The hackers can even bring the software with a pen drive allowing the user to hack password or other confidential information.Spreading virus:Earlier, floppy drives and emails were considered as main source of virus to computers. However, there has been anti-virus software developed to counter virus and protect the PC. But with pen drive it is difficult to check the virus with the safeguard as the device can bypass the protection. It is almost impossible to defend against the viruses unless and until you have strong anti-virus policies or you are not scanning all files in your network. It is easy for a virus writer to corrupt the entire network of a corporate environment with a pen drive.Plant malicious software:Virus apart, it is not difficult for anyone to take any spamware and plant it in the PC. In corporate sectors the threat multiplies when employees use pen drives to bring unauthorized software or any other data such as software pranks, sharewares, mp3 files, pornography pictures, video clips and other inappropriate data that is against the corporate ethics. As pen drives allow more space, it is easy to bring bulky software which impossible with a floppy. Situation worsens when the software is used to crack password.Causing data loss:Pen drives barely allow any security system in terms of password or any other built in security feature. So it is more likely that if a person loses a pen drive, the data inside it can be accessed by anyone. If it falls in wrong hands he or she can misuse it. a pen drive can be easily stolen or misplaced and the data stored inside it can be easily manipulated. There have large demand for pen drives with some security systems such as finger-print reader or protective software.There has been a conscious protest against pen drives in many private and government organization. Though it is a convenient device for the productive brains, it has proved to be beneficial for the thieves as well. Pen drives are small in size and have greater capacity to store information. Hence the thieves can carry the device stealthily in pockets and take information.Unless and until any drastic step has been takes against it, the security of any organization can be in stake. Even a visitor can retrieve data easily from an open computer. Considering these threats, some companies have taken some protective measures for their security by banning pen drive inside company premises. It can reduce the threat to some extent.

Variations Of Software Programs

Author: James Brown
Consumers are enthralled by the software installed in electronic devices because these programs allow them to be more productive and provide them with a source of entertainment that is suitable for every member of the family. Some electronic devices will not work at all without the software installed, and others work better because the software programs have been added since the device was bought.

People are more familiar with the software programs that run their personal computers, but other digital devices are equipped with software. The operating system software is the controlling force behind all computer operations, This software allows the user to perform independent tasks using word processing software programs, or includes software that will allow the user to complete complex mathematical calculations using formulas in spreadsheet formats.

The operation of this type of software is independent of any other type of custom software that has been installed on the computer. Many computer users must install software that allows them to view videos and graphics. These software programs are easy to download but will require update to be installed from time to time to keep the software program running smoothly.

The software updates are written with scripting software that simplifies updates by creating screens that are presented in an easy to understand language that requires the user to click a few buttons and step back while the software does the rest of the installation on its own. Other software is embedded into the installation program that will notify the computer user that the installation is complete. In most cases, the computer software will require that the user restart the system for the changes to go into effect.

Some customized software programs will be created for businesses to track inventory or provide a certain service to a client or the public at large. Some computer operating systems work on the Windows platform and other software program are open source and can be edited by users who know the coding used in the software programs. These programs can be modified by each user and uploaded to the site where it was obtained so that other users can benefit from the changes that were made.

People prefer to use open source software because it is available for download through internet websites. The open source software is considered freeware and is the product of computer users who have a talent for creating programs that enhance productive tasks found in other software or the software could be scripts that make mundane tasks tolerable and easier to complete. Some programming artists create freeware to establish a web presence and build a business from software popularity.

The software programs installed on electronic devices allow people to connect to the internet and the user will have all the tools and storage space required to download files from a computer at work. The PDA devices contain software that will also allow users to check email and store it for future reference. Some personal digital assistants are equipped with software that allows people to access maps and obtain directions to a desired destination.

Fighting Off Viruses: Advancements In Antivirus Software Suites

Author: N. Robbins
Protecting your computer from a virus is getting harder and harder each day. While it may border on the paranoid, it goes without saying that you can't leave your guard down for one second. Even corporate giant Microsoft has found its own systems compromised on more than one occasion.

Remember the "good old days", before the advent of the Internet and downloadable programs? Life was simple then in terms of computer viruses. With the primary way in which a virus could be transmitted being limited to floppy disks, the ability to catch and eradicate the virus was a lot easier. By today's standards, it used to take quite a while before a virus was able to infect a computer and slow down the system. The antivirus software of that time was typically able to identify and eradicate viruses before they caused too much damage. Additionally, computer users were pretty savvy on how to protect themselves in terms of scanning all floppy disks before copying them to our desktop.

The Internet helped change all that. The Internet provided a conduit by which viruses could move from host to host with lightening speed. No longer could a computer user just worry about floppy disks as points of entry, but they now had to worry about email, email attachments, peer-to-peer file sharing, instant messaging, and software downloads. Today's viruses can attack through multiple entry points, spread without human intervention, and take full advantage of vulnerabilities within a system or program. With technology advancing everyday, and the convergence of computers with other mobile devices, the potential of new types of threats also increase.

Protecting Your Computer

Luckily, the advancement of antivirus software has kept pace with current virus threats. Antivirus software is essential to a computer's ability to fend off viruses and other malicious programs. These products are designed to protect against the ability of a virus to enter a computer through email, web browsers, file servers and desktops. Additionally, these programs offer a centralized control feature that handle deployment, configuration and updating.

A computer user should remain diligent and follow a few simple steps to protect against the threat of a virus:

1. Evaluate your current computer security system.

With the threat of a new generation of viruses able to attack in a multitude of ways, the approach of having just one antivirus software version has become outdated. You need to be confident that you have protected all aspects of your computer system from the desktop to the network, and from the gateway to the server. Consider a more comprehensive security system which includes several features including antivirus, firewall, content filtering, and intrusion detection. This type of system will make it more difficult for the virus to penetrate your system.

2. Only install antivirus software created by a well-known, reputable company.

Because new viruses erupt daily, it is important that you regularly update your antivirus software. Become familiar with the software's real-time scan feature and configure it to start automatically each time you boot your computer. This will protect your system by automatically checking your computer each time it is powered up.

3. Make it a habit to always scan all new programs or files no matter from where they originate.

4. Exercise caution when opening binary, Word, or Excel documents of unknown sources especially if they were received during an online chat or as an attachment to an email.

5. Perform regular backups in case your system is corrupted. It may be the only way to recover your data if infected.

Recommended Antivirus Software

There are numerous applications available to consumers. With a little research, you can pick the program that is right for you. Many programs provide a trial version which allows you to download the program and test its abilities. However, be aware that some anti-virus programs can be difficult to uninstall. As a precaution make sure to set up a System Restore point before installing.

Here are a few programs which typically receive high marks in terms of cost, effectiveness, ease of use, and customer service.

The Shield Pro 2005™ provides virus protection and hacker security through ongoing support and updates. When a virus breaks out, The Shield Pro 2005™ promises to provide a patch within 2-3 hours and a fix for the virus within 5 hours. You can set your computer to update viruses weekly and run a complete virus scan.

BitDefender 9 Standard provides antivirus protection, as well as Peer-2-Peer Applications protection, full email protection, and heuristics in a virtual environment. This provides a new security layer that keeps the operating system safe from unknown viruses by detecting malicious pieces of code for which signatures have not been released yet.

Kaspersky Anti-Virus Personal 5.0 program is simple to install and use. The user only needs to choose from three levels of protection. It allows updates as frequently as every hour while promising not to disrupt your computer. The program also offers a two-tier email protection feature and round-the-clock technical support.

PC-cillin Internet Security combines antivirus security and a personal firewall-for comprehensive protection against viruses, worms, Trojans, and hackers. It also detects and removes spyware and blocks spam. It even guards against identity theft by blocking phishing and pharming attacks.

AVG Anti-Virus Free Edition is a free downloadable antivirus program that has received high marks for its reliability. In the past, free downloadable antivirus programs have been viewed skeptically because of issues relating to its reliability. However, AVG from Grisoft, remains one of the best-known free anti-virus programs available. While AVG can not be installed on a server operating system and there is no technical support, it still makes a good choice for many home computer users. The best part is that since it is free, you can try it with no further obligation necessary.

Diagnostic Computer Software And Programs

Author: James Brown

Most people do not realize that they have a problem with the operating system for a personal computer until they get an error message when the computer is turned on one day. Before the computer system reaches this stage, the computer user might notice that the system has slowed considerably over a period of weeks and that the keyboard or other input devices work incorrectly and gibberish is written across the computer screen.

The error message could come in a numeric form that lists an error code or it could come with a blue screen showing on the computer monitor that alerts the user to a fatal operating error that will prevent the computer operating system from loading. A computer user might try to reboot the operating system several times with the same result. Then they might consider using a recovery disk that contains diagnostic software on it that could identify the source of the problem.

Some computer operating systems require users to access diagnostics software by repetitively hitting the F8 key on the computer keyboard. This procedure will take the operating system into a safe mode that will allow the operator to perform several diagnostics on the computer system itself. Some programs might now operate normally while in safe mode, but if the errors are found and repaired, the computer system should load normally on the next restart.

Using this type of diagnostic computer software will require an understanding of error codes and settings by which the computer operates. The user manual will have a complete listing of error codes and the list will also explain what they mean. While the computer is operating in safe mode, the operating system will offer the computer operator several choices on the computer screen that will help repair the errors that are on the hard drive of the computer.

Changes should be made sparingly to the computer while it is operating in safe mode. Any numerical changes that occur to the hard drive will directly effect the way the computer system will respond when it is restarted. Some changes will make the computer inoperable and all information on the system could be corrupted and will be unusable. Every computer user should activate the system restore option under the system icon of the control panel when they purchase the computer.

The system restore selection will allow the diagnostic software to restore the system to an earlier time, and is especially helpful when the system stops working after new software or hardware has been installed. The computer systems restore diagnostics software program is an important system tool that many users forget to start. The restore settings will make recovery of materials easier if the system stops responding due to infection by computer viruses or corrupted software.

If the diagnostics software fails to repair the system, then the user is faced with reinstalling the operating system from operating disks that are provided with each new computer system. A good rule of thumb to follow is to back up information on a daily, weekly or monthly basis to ensure that no data is lost. There are many software programs for data recovery on the market to help recover data when the operating system diagnostics programs fail to solve the problem.

Sony Ericsson K510i - Fortus Mobile Phone Review

Author: Martin Fortus
Mobile Simplicity

Simple and functional, with a stylish design and affordable price tag, the Sony Ericsson K510i is the ideal phone for budget mobile users who need an affordable handset with all the basic features. The K510i is a great looking mobile phone with a little of everything. Unfortunately, this handset doesn't really excel in any area.

At first glance, the K510i could easily be mistaken for a high end mobile phone. The handset is available in two colours, a sophisticated and sleek midnight black or a trendsetting, stylish polished purple. The K510i is a compact candybar phone that is lightweight and quite comfortable to use. The large TFT display screen provides full colour resolution and the keypad is evenly spaced and easily distinguishable. The keys are somewhat small, which could be troublesome for users with large fingers and Sony has continued to use the fidgety joystick navigation found in earlier Ericsson handsets.

The Sony Ericsson K510i may look like a cutting edge mobile phone and it is loaded with features, but the feature line up is extremely basic. The camera, a 1.3 megapixel, is great for photo caller ID and capturing images and video for multimedia messaging, but there is no flash so photos in low light are useless. The camera does include a variety of fun imaging functions, including image warp and a picture editor.

The music player built into the K510i is typical of Sony Ericsson mobiles. It supports most common file types and sounds terrific. The K510i is not going to take the place of a dedicated mp3 player, however, because of the unfortunate lack of expandable memory. With only 28 Mb of internal memory and no card slots, you will be lucky to store more than 5 or 6 songs on the phone.

All the common productivity and personal organization tools are included on the K510i. A calendar, alarm clock with snooze, support for conference calling and email, and java games are all part of the feature line up. The K510i also features a wide range of connectivity options, including Bluetooth, USB, infrared, and fast port. Battery life is average and call clarity is quite clear.

It's quite clear that Sony Ericsson did not go all out with this model, but they have reached a level of comfort with their handset production where they can quickly produce a quality phone without too much sweat expended. In this case good enough is still good enough, but the competition is getting stiffer and Sony needs to look out.

Those looking for a superb camera phone or searching for a mobile with extended media capabilities should probably look elsewhere. If you want a great looking handset that is fun and easy to use, the K510i could be the phone for you. The Sony Ericsson K510i is stylish and compact and it is quite affordable. It may not have the best camera, memory is too limited for the K510i to be a very useful music player, but it is a terrific handset for those in need of the basics in a durable, quality mobile phone.

Laptop Rental Guide

Author: Barry Byers
Laptop rentals are a great option for busy professionals who need an affordable solution for training, traveling, tradeshows and trial runs.

• If you are attending a training session off-site, renting a wireless-enabled laptop allows you to stay in touch with the office and keep up on work while you are on breaks. Laptops are also great for taking notes or storing documents distributed at the training.

• If you are conducting training and require the same configuration for all attendees, laptop rentals are the answer.

• Frequent business travelers will tell you that they cannot function without their laptops. But what if you travel only occasionally? Chances are your company will not want to invest in a laptop if you only go on a couple of trips a year. Laptop rentals are ideal in this situation. You can rent a machine and even have it delivered to your destination, saving you from having to carry it with you.

• Laptop rentals also help in a tradeshow exhibit booth. Laptops are easy to carry to and from the exhibit site. Their portability is also a plus when you want to meet one-on-one with a potential client after the exhibit hall closes. Laptop rentals also make the newest technology affordable - a new laptop with a high-resolution screen is much more impressive than older models that show their age.

• What if you are considering a laptop purchase? It is very difficult to know which brand and model will suit your needs unless you can use it in a real-world situation. Laptop rentals let you take a new computer for a trial run for a few days or a couple of weeks. Try a few models and make an informed decision before you buy.

Before you find a vendor for your laptop rentals, take note of the following considerations:

• What happens if you need to make changes to your rental agreement? Ask about the company's policy on changing the end date of the agreement.

• How will the laptop be configured? Will the vendor load software for you, or take into account any other special requirements?

• What kind of support does the vendor offer? You do not want to be left alone on the convention floor with a booth full of inoperable equipment. Ask about phone and on-site support.

• What range of products does the vendor offer? You may have specific needs for laptop rentals, perhaps requiring several of the same model for an upcoming tradeshow or training session.

• What kind of lead time does the vendor need for laptop rentals? If you need a laptop fast, can they handle it?

• Where does the vendor deliver? Often vendors with a national reach are the ones with the infrastructure required for "anywhere, anytime" deliveries.

Always remember that the buck stops with you. If your equipment malfunctions during a presentation or training, your audience won't be amused. Take the time to go test your laptop while your computer rental company is present and make sure you can reach them if something goes wrong.

What Are The Benefits Of Using Microsoft Sharepoint Server?

Author: Amy Nutt
One of the most popular software packages for businesses today is Microsoft SharePoint Server. Microsoft SharePoint Server is a very popular program for businesses, because it helps to improve business processes without the requirement of extensive training beforehand. SharePoint was created several years ago as a tool for creating corporate portals that serve as entryways to documents such as human resources forms, but more recently, it has expanded functionality and split. SharePoint is part of the foundation of a broad rethinking of the way office workers use computers. The suite supports a large number of programs and is built to be an effective content management platform for business use. It is also designed to streamline many different types of business applications, allowing the users to be more effective in their day to day functions. Many different types of users would be able to use Microsoft SharePoint Server effectively and the platform allows for easier control of many business processes.

One of the largest benefits to using Microsoft SharePoint Server is the ability to manage and control the content that is entering or leaving your business.

Determining Coin Values

Author: HBHB
Factors that Influence the Value of Collectible Coins

If you are interested in collecting coins, it’s important to be able to have a rough idea of how much coins are worth. Knowing how coin values are determined will enable you to find good deals, and ensure that you don’t get cheated into paying too much money for a coin with a low worth.

Supply Influences Coin Values
One major factor in determining coin values is the law of supply and demand. If there are many coins of a particular type available, that coin will not be worth much. On the other hand, if only a very few coins of that type are produced, the coin values will rise. This is why a completely normal-looking copper penny minted in 1943 is worth about $200,000, whereas a 2,000 year old Roman coin may be worth less than $100 – because thousands upon thousands of Roman coins were minted, but only 40 pennies produced during war-time 1943 were made out of copper.

Demand’s Effect on Coin Values
Even among coins with a similar number of copies in existence, some have a higher worth than others. This is because some coins are in higher demand, driving up the coin values. Coins may become popular because they are particularly lovely to look at, because they are part of a topical set that is often chosen by collectors, or because they have a certain historical significance.

Precious Metals and Coin Values
Some coins are made out of precious materials like gold bullion or platinum. These coin values are less volatile because the worth is guaranteed in part by the material. A gold bullion coin, for example, is usually worth more than its melted weight, but it is never going to be worth less.

Coin Values are tempered by Grade or Classification
The final major factor in determining coin values is the grade or classification of the coin. The more wear and tear that a coin has undergone, the less value it is going to have. This is why un-circulated coins are usually more valuable than coins that have been passed from hand to hand. Un-circulated coins have always been kept in the very best of conditions, making their value much higher. A coin in flawless condition may be worth hundreds of times more than a low-grade version of the exact same coin.

Now that you understand the basic factors that influence coin values, you have a better grasp of which coins may have real value and which will be worthless. In order to get a ballpark estimate of the value of any coins you might have, you will first need to determine its grade or classification. You can do this by comparing your coin’s condition to a published list of guidelines. Then look up the value of a coin in that condition in a book such as “The Standard Catalog of World Coins,” which should be available in most public libraries. If you need to know the exact amount that your coin is worth, you should take it to a coin dealer and let him or her evaluate it for you.

6 Good Reasons for Online Backup Services

Author: Thom Davidson

Seven (7) advantages of online backup services include:

1. Automatic. Once one establishes their schedule, it is fully automated. There are no tapes to manage, staff to schedule, or vendors to coordinate for pickup and delivery of tapes. Therefore, you save time, money and virtually eliminate errors.

2. Secure. Data is stored on disk and not tape. Tape has a history of failure and it typically occurs at the most inopportune moment. In addition, most tapes are not encrypted. One can only imagine the potential ramifications to your business if customer records were accessed by someone using one of your unencrypted tapes. The story is not much better if you are unable to recover critical data at vital point in time. Online backup services can offer end-to-end encryption AES algorithms that are used both in transit as well as storage. This further ensures the security of your sensitive data. With the online backup service your sensitive data is also automatically stored offsite in a secured data center.

3. Accessible and Managed from Anywhere. “A centralized system that allows you to manage your entire systems backup and recovery requirements regardless of where they or you are located is a huge advantage to companies. This is particularly true for companies with multiple locations.” Says Jim Kandrac of VAULT400. Popular platforms and applications being managed in this way by leading providers include DB2 – System I, AS/400, iSeries, AIX, HP UX, SUN, Exchange, SQL, Windows, VMware, Linux, etc. Netware and Mac.

4. Efficient Use of Internet: Some of the better online backup services back up only the data blocks in new or changed files, resulting in significantly faster backup times and minimal. Data is also compressed before transmission. In addition they might offer bandwidth throttling. This allows one to define how much of their Internet bandwidth they want to allow to be used for this process during various time windows of the day. For example, you might limit the process to a maximum of 10% of your bandwidth during normal office hours and open it up to 80% for the balance of the day.

5. No Capital Investment: If you are like most organizations, getting approval for a large capital expenditure is a daunting task. With the Software as a Service (SaaS) approach one is basically paying a monthly fee for the service. In addition the startup can be almost immediate. Typically, a small software agent is loaded on the systems you wish to backup to a data vault and then the scheduling/backup process can begin the same day.

6. Compliance Regulations: The recent increase in government and industry specific regulations (SAS 70, Gramm-Leach-Bliley Act, HIPAA, SOX and SEC|NASD) surrounding the privacy, accessibility, and retention of information are creating new challenges for backup and recovery processes. Vendors like VAULT400 are intimately familiar with these challenges. They give organizations confidence that their critical information is securely stored for as long as necessary, yet quickly accessible when needed. This immediately addresses inquiries by auditors and security/privacy concerns.

Summary: As you can see, there are some very compelling reasons for an online backup service. Remember, the goal of any online backup and recovery plan is to maintain the integrity of your systems and your business with little or no interruption in the process. When a disaster does occur, we want business to remain uninterrupted at best, or at worst get back on line in a short amount of time. With an online backup service you can quickly transfer your data to any targeted system from anywhere in the world and stay in business.

Know More About Load Balancing

Author: Amy Nutt
Load balancing, by definition, is the process of spreading the amount of work that is conducted by a computer system between a number of different computer systems to increase the speed that the work is completed in. There are several different methods in which load balancing can be accomplished by and the technique can use many different types of computer components, including both hardware and software applications. Load balancing is typically completed using a cluster of computer servers that may or may not be located in the same location. Some load balancers provide a mechanism for doing something special in the event that all backend servers are unavailable. This might include forwarding to a backup load balancer, or displaying a message regarding the outage. Load balancing can be useful when dealing with redundant communications links.

There are many different companies that see the benefits of using load balancing and implement the procedure for their companies. Companies that conduct business transactions in large numbers using the internet are prime candidates to use load balancing to ensure that all of their clients and customers will be able to conduct their transactions in a quickly and accurately manner. Companies that need to network a great deal of computers for individual users also typically use load balancing to ensure that all computers will work properly and have the right amount of power to be able to perform the functions that they are intended to perform. It also ensures that the company will still be able to do business if one server becomes corrupted or goes down for an extended period of time.

There are several different methods that are widely used for load balancing. One of the most popular methods of load balancing is Global Server Load Balancing. This technique distributes the incoming tasks to a group of servers in a particular geographic location. This technique is widely used by companies that have a global presence and have a need to satisfy customers or employees in many different geographical locations. Using Global Server Load Balancing ensures that the work load is distributed throughout the entire server system in an easy to manage manner and ensures that all geographical locations are obtaining the correct information from the correct set of servers.

Another load balancing technique that is commonly used is called Persistence Load Balancing. This technique assigns each new client to a different server in a round robin (distributed page requests evenly to one of three Squid cache servers) type of allocation. This client is then assigned to this specific server for the future of their relationship with the business. This ensures that no one server is overloaded with a particular type of client, such as those in a certain geographical area or use a specific type of service and ensures that the clients are distributed evenly through out all of the servers that the business possesses. These server assignments are typically monitored by using the customers IP address as the customer's unique identification code.
