The single biggest improvement in the history of the computer could be the development of the first microprocessor. This little chip allows a mind boggling amount of processing power to be packed into a very small space. Space is one of the biggest limiting factors in actually assembling a computer at a reasonable price. By being able to pack more and more processing power into a smaller area, the strength of modern computing is able to expand exponentially through advanced chip development.
The first microprocessor chip was invented by Intel back in November of 1971. This little chip was crucial to new development. Integrated circuit technology had opened the door for advanced computing that was only limited by the amount of chips that could put together.
This chip, the 4004, made the crucial development step of managing to pack all of the computer's "brain" into one part. This small microprocessor contained the full power of the central processing unit while also providing for the computer's basic memory and the control methods for incoming and outgoing data. This progress was simply amazing when one considers that the company was just a little start up by two engineers.
This chip was actually the development of a rather normal contract assignment for Intel. They received one of their first jobs to design twelve different computer chips for Busicom, a small Japanese company. They wanted designs for chips that would provide for keyboard scanning functionality, controlling the display on the monitor and the printer and just about anything else that their brand of calculator hoped to do. There was just one big issue that they had to overcome.
They needed the money but faced an interesting issue. They lacked the sheer manpower necessary to actually design twelve chips in the time frame. So, their engineers figured out a way to build one chip that was able to do every single function. Busicom liked the idea and decided to fund the project. Time passed and a new chip that had more power than any of the old computers was developed.
Ironically, they decided to buy back the design from Busicom, which subsequently went bankrupt, leaving them completely in control of the new technological breakthrough in electronic parts. The sky was the limit from this point onward. This basic technological idea has been applied time and time again to give us electronics capable of amazing power and ability.
The average calculator now has more processing power than was required to plan the first missions to the moon. The shrinking of this technological power has worked perfectly alongside the development of many other electronic parts to make everyday life just a little bit easier for everyone. In just the time span of about 40 years, we have advanced to computers that are almost able to mimic true human intelligence.
These advancements in micro processing have improved all of our lives in ways that we may not even realize. The power of a computer is now literally at our fingertips.

The Rousing History Of Microprocessors
Finding Electronic Parts With Ease
There are many different reasons to find special electronic parts in your everyday life. We live in a world powered by electronic equipment capable of powerfully improving our lives. Kitchens are powered by advanced appliances capable of cooking, steaming, chopping, grilling, deep frying, broiling, or boiling a meal.
Once it's over, you just scrap the plates and wash them in the dishwasher. But all of these wonderful devices can easily break and then you will have to get into their electronic guts to try and repair them.
Finding these parts can be particularly difficult though. Many companies only offer limited support for replacements since there isn't much incentive. Why should they focus on technology that is five years old, when they can be focusing on the technology that powers next year's machines?
Technology is advancing at such a rate that the individual bits and pieces are not able to actually keep up. Pieces are phased out and replaced with new models that are completely incompatible with older models. So, how will you find a replacement?
If you are one of the lucky ones, then the manufacturer will still offer a normal replacement piece. Using a brand new piece can have some very nice benefits. You will effectively be guaranteed of it working right, even if there are a few kinks in the installation process. It is also much easier to make a call to a manufacturer than to browse through spare parts. This isn't very likely though, and you will probably have to look for other alternatives to find the piece.
There are many options available to find electronic parts. You should start by looking for any electronic surplus stores in the area. Technology is advancing at a rate that involves a good amount of appliances and equipment being thrown away just to make room. This means that their loss can be your gain, if their equipment was collected or purchased by the store. If you go to one of these stores you need to have a good idea of what you need.
Don't just look at your part once and say that "I'll remember it." You won't. If possible take a picture or the actual broken part with you so that you can actually match it with the replacement. Nothing is worse than buying the wrong model just because it looked like the right one.
Once you find your piece, check it out and make sure that it isn't broken as well. A good surplus store might have a warranty option available for it. Most of them have a steady supply of electronic parts and they won't argue over replacing a broken item.
Not everyone can find their part at a local store though. In this case, you may have much better luck online. If all else fails, you can always look on eBay. A good number of surplus sellers across the country are smart enough to greatly expand their market by offering some of their unique wares online. You can easily find a great deal through a respected seller. Then your part will be safely shipped to you at a price that you can afford.
Finding the right electronic part can be particularly annoying. Hopefully these two options can give you some places to start your search.
