Question

Explain CPU with block diagram.

Answer 1

...CPU is Central Processing Unit. 

.✓✓ it is also known by the name of processor, microprocessor or a computer processor. 

..✓✓✓A CPU is an electronics circuit used in a computer that fetches the input instructions or commands from the memory unit, performs arithmetic and logic operations and stores this processed data back to memory.


Components of CPU:


Control Unit

The Control Unit is an internal part of a CPU that co-ordinates the instructions and data flow between CPU and other components of the computer. It is the CU that directs the operations of a central processing unit by sending timing and control signals.

Arithmetic Logic Unit

The ALU is an internal electronic circuitry of a CPU that performs all the arithmetic and logical operations in a computer. The ALU receives three types of inputs.

Control signal from CU ( Control Unit )

Data(operands) to be operated

Status information from operations done previously.

When all the instructions have been operated, the output that consists of data is stored in memory and a status information is stored in internal registers of a CPU.
