Internal Structure of Computer

All Computer System Perform the following five operations:-

Inputting, Outputting, Processing, Storing and Controlling.

 

Input Unit- This is the unit by which or information entered. Various

Input devices accomplish this task such as keyboard mouse.

Output Unit- It is responsible for giving the result. Various output devices accomplish this task such as printer, VDU (visual display unit), Speaker, etc.

Storage Unit- This unit Provides space for storing and instruction space for intermediate result and also space for final result.

Central Processing Unit (CPU) - The control and arithmetic logic unit of a computer system are jointly Known as the Central Processing Unit.

Arithmetic Logic Unit (ALU) – All arithmetical (Addition, Subtraction, Multiplication, Division) and logic (decided) Problem solved in this unit.

Control Unit (CU) - Control unit controlled all the operation. Such as how does the ALU know what should be done with the data once they are received, how the final result (not intermediate result) shall be sent.

The microchip is the heart of computer that actually does the work. It also Known as the processor or CPU (central processing unit). It is install on the motherboard inside the computer. There are different types of Processor available in the market Pentium (P₁, P₂, P₃, and P₄) AMD, Celeron,etc.
