Block Diagram of Computer System ::The Computer systemconsists of mainly three types that are central processing unit (CPU),Input Devices, and Output Devices .

1.Input Devices ::

The set of instruction or information is provided to the computer system or PC with the help of input devices such as (keyboard, mouse, scanners etc). The Instruction or data presented to computer system is converted into binary form then it is supplied to computer system for further processing .

2.Output Devices ::

Output devices of computerproduce or generate results with the help of devices or gadgets such as printer,monitor etc primarily these instruction or data provided to computer system is in binary code so to produce or generate the desired output the system has to convert this data into human-readable form, to do so it has to first present the data or instruction to computer system for further processing or handling.

3.CPU:The CPU is the heart | Brian of a computer because without the necessary action taken by the CPU the user cannot get the desired output. The central Processing unit [CPU] is responsible for processing all the Instruction which is given to computer system or PC. B
