Analog Computer

They are used to measure physical states, by which pressure, temperature, voltage, and speed are measured, which are constantly changing.
Examples of this are Voltmeter and Ammeter.

Digital Computer

These are in contrast to analog computers and these computers use the binary number system, in which data is processed in the form of 0 and 1. In this computer also work can be done like an analog computer, this computer is usually used the most.
Examples of this are desktops, Personal computers, Workstations, tablets, etc.

Hybrid Computer

By this the work of both analog and digital computers can be done, this computer has the functionality of both computers, and this computer is mainly used in scientific calculations, large industries, and defense systems.

Types of computers Based on the purpose

Based on the purpose, the computer is mainly divided into two parts:

General Purpose Computer

Through this computer, we can easily do various tasks in our daily life.
Examples of this are desktops, smartphones, and tablets.
