Basic Structure of Computer
All types of computers follow a same basic logical structure and perform the following five basic
operations for converting raw input data into information useful to their users.
Following diagram shows the basic structure of Computer:
Input Unit
This unit contains devices with the help of which we enter data into computer. This unit makes link
between user and computer. The input devices translate the information into the form
understandable by computer.
CPU (Central Processing Unit)
CPU is considered as the brain of the computer. CPU performs all types of data processing
operations. It stores data, intermediate results and instructions (program). It controls the operation
of all parts of computer.
CPU itself has following three components
ALU (Arithmetic Logic Unit)
Memory Unit
Control Unit
Output Unit
Output unit consists of devices with the help of which we get the information from computer. This
unit is a link between computer and users. Output devices translate the computer’s output into the
form understandable by users.
