CPU is the central processing unit that can execute the computer programs. It is a logical machine and the execution of computer programs is the major role which it plays in computers. CPUs have been in use for many years but their designs and implementation varies over the period of time. CPU is the heart of the computer and it contains all of the important components of computer like Motherboard, processor, Hard disk and CD-Rom. Every process in the computer is possible only through its CPU.
CPU is responsible for executing a sequence of stored instructions which is known as a program. These programs are stored in computer memory. CPU in four steps process including, Fetch, Decode, Execute and Writeback, completes its operation. In this way computer can never work without a CPU.
