A processor ( CPU ) is an integrated circuit ( IC ). The processor consist of millions of IC chips and each IC chip consist of millions of tiny component called transistor. The Transistor is madeup of silicon which is a semiconductor material .
The processor ( CPU ) controls all the activities of the computer system. And therefore it is referred as brain of the computer system. There are two main computer processor manufacturers Intel and Advanced Micro Devices ( AMD ). These two companies produce most of the processors used in desktop, laptops and notebooks.
A Central Processing Unit ( CPU ) performs millions tasks per second to execute a computer program by performing the basic arithmetic, logical, control and input / output ( I / O ) operations as specified by the program instructions.
A CPU is placed on the motherboard in a processor socket with locking liver mechanism in order to fix the processor chip properly into the processor socket . The processor socket contains a IC socket in which the processor chip is firmly mounted . A heatsink is mounted on the top of the processor chip which protects the processor from excessive heat generated.
