What is CPU?
If you are on the market for a new computer, you need to understand the CPU function. The CPU, also known as a central processing unit or processor, is essentially the "brain" of your computer. Without a CPU, you couldn't play games, a type of research articles or surf the Internet. Your computer would be basically very expensive paper. However, the CPU is an internal part of the computer. You do not see it from the outside of the system; You would have to look inside and remove both CPU cooler and fan to look well.
The first CPU was used in the early 1960s. They were tailored as part of a larger computer, which makes them disproportionately expensive. Once the engineers figured out how to produce CPU in bulk, personal computers have become more accessible to the average American. With the introduction of an integrated circuit at the end of 70. This helped transform computers from large, bulky devices that occupied the entire rooms into more manageable models of desktop computers and laptops.
Today, Intel is the most famous manufacturer of computer processors. No matter what type of computer you have, your CPU works by performing a series of stored instructions known as a program. Most CPUs correspond to von Neumann architecture, which says the CPU must load, decode, perform and write data in a relatively fast sequence.
Because the CPU is one of the most important parts of the computer, it should not be any surprise that it is also the most expensive. In fact, if your computer is older than three years and your processor has been damaged by static electricity or other factor, you may want to consider upgrading to a brand new computer. Newer and faster CPUs often provide Enough with additional computing performance to make the purchase a wise investment.
CPU is sometimes called microprocessors, although these two terms are not completely interchangeable. Microprocessor, first introduced in the 70s, reduces the size of the word cpu from 32 BITs for 4 bits in an effort to allow transistors of logical circuits to fit into one part. Performing all CPU functions often requires more than one microprocessor. Microprocessors are also commonly used in mobile phones, cars and electronic toys.
