Microprocessors

A microprocessor, or central processing unit (CPU), is located on the motherboard of a computer, where it receives and executes instructions from computer programs which have been activated by the user. The design and use of the CPU has changed dramatically since earlier models, but the fundamental operation has remained the same; to process all information and instructions going in and coming out of the computer.

Older model CPU’s were larger in size than modern processors, and were typically custom designed as part of a larger, sometimes one of a kind system. But this method of custom designed CPU’s became very expensive very fast, this lead to the development of mass-produced processors which were designed for variety purposes, rather than just one. This became a very popular trend as mini, and micro computers became increasingly popular, which allowed the processors to become much smaller in size. As technology has advanced the CPU has also become much faster with newer processor speeds being measured in Gigahertz, as apposed to earlier models whose speed was measured in Megahertz.

With CPU’s becoming smaller and faster, their presence has expanded to many other digital devices that we use in our every day lives, and has come a long way from the days where the only application for a CPU was in a dedicated computing system. Now we see microprocessors in thing like cars, cell phones, and even in some children’s toys. As technology continues to advance these little chips will be found in almost anything and will be faster than ever. That is all I have for this week, check again next week for more computer hardware profiles.
