THE GOOGLE DEFINITION SAY’S…
…A
central processing unit (
CPU) is the electronic circuitry within a computer that carries out the instructions of a computer program by performing the basic arithmetic, logical, control and input/output (I/O) operations specified by the instructions. .
A CPU work’s typically where a user can never look to it’s working or processing. A CPU Basically Converts the Input given by a user to a needable output. Now In a More Simpler Way … If a computer operator is Pressing any Key on the Keypad which basically appears on the screen --- Yes It is the CPU of a computer which is performing the action which is pressing the key .Every Calculation which a user does For eg PLUS,MINUS,DIVISION… Which are Known as Arithmetic Logical operation are all performed by CPU. CPU Manages the various components of the computer which is Known as Central Unit(CU). CPU
Generally,CPU is a combination of Arithmetic logical unit (ALU) and control unit(CU).where Arithmetic logical unit is the unit where where all the calculation and comparison is done. It is the unit where all the instructions are performed and control unit(CU) maintains the operation of the entire systems manages,co-ordinates entire system.
Inside It Consist various Part which has their own Function’s and operation such as Random access memory(RAM),Read only memory(ROM),MICROPROCESSORS, Storage unit etc. Explantion’s of some of them is given Below
Random Access memory: It Stores Frequently Used Program Instruction to increase the speed of operation. It is a volatile memory
Hard Disk: Storage Device of computer
Microprocessor: It Holds The Information about the OS(operating system) of a computer
AND MANY MORE……..SUCH PARTS OF CPU WHICH PERFORMS VARIOUS OPERATION’S
