1. Input Unit:
It is a device through which we enter the program and data into the computer. The data is then stored and processed with the help of programs.
2. Central Processing Unit:
The Central Processing Unit (CPU) is divided into three units namely, the control unit, the arithmetic, and logic unit and the memory unit.
3. Control Unit:
This unit is considered to be the nervous system of the computer. It controls all arithmetic operations to be performed. It also coordinates the functions of all hardware units of the computer.
4. Arithmetic and Logic Unit (AL U):
This unit performs all arithmetic calculations and logical operations involved in the program.
5. Memory Unit:
The function of this unit is to store the data and the set of instructions given by the programmer. The computation results are stored in the memory and they may be used for subsequent computations or sent to the output unit.
6. Output Devices:
Output devices receive information from the CPU and present it to the user in the desired form. Some common output devices are visual display unit (VDU), Printer, etc.,
