Block Diagram of Computer
Computer Block Diagram System: Mainly computer system consists of three parts, that are central
processing unit (CPU), Input Devices, and Output Devices. The Central Processing Unit (CPU) is
divided into two parts again: arithmetic logic unit (ALU) and the control unit (CU). The set of
instruction is in the form of raw data.
A large amount of data is stored in the computer memory with the help of primary and secondary
storage devices. The CPU is like the heart/brain of the computer. The user does not get the desired
output, without the necessary option taken by the CPU. The Central processing unit (CPU) is
responsible for the processing of all the instructions which are given by the user to the computer
system.




The data is entered through input devices such as the keyboard, mouse, etc. This set of instruction is
processed by the CPU after getting the input by the user, and then the computer system produces the
output. The computer can show the output with the help of output devices to the user, such as
monitor, printer, etc.
