The Microprocessor

 The Microprocessor

 The Microprocessor is the brain of the computer,which is developed in many years using different technologies.A microprocessor also know as the CPU or Central Processing Unit is a collection of complex circuits on a single chip.The first microprocessor was the Intel 4004,Introduced in 1971.The 4004 was not very powerful,all it could do was add and subtract,and it could only do that 4 bits at a time.

The first microprocessor to make it into a home computer was the Intel 8080,a complete 8-bit computer on one chip,Introduced in 1974.The first microprocessor to make a real change in the industry was the Intel 8088,Introduced in 1979,and incorporated into the IBM PC(which first appeared around 1982). Then it evolved from the 8088 to the 80286 then to the 80386 then to the 80486 then to the Pentium then to the Pentium 2 then to the Pentium 3 then to the Pentium 4. All of these microprocessors were made by Intel and all of them are improvements on the basic design of the 8088The Pentium 4 can execute any piece of code that ran on the original 8088,but it does it about 5,000 times faster!
