Let us now take information about each computer.

Types of Computers (Based on Application)

1. Analog Computer

An analog computer is a machine that shows a physical quantity of data (pressure, temperature, length, height, etc.), these data are constantly changing.

The efficiency of this computer is fast. We get their result in the form of graph etc. Analog computer cannot store data. They are used in the fields of technology, science, education etc.

Thermometer is an analog computer.

2. Digital Computer

This computer is different from analog computer. A computer that processes information in digital form is called a digital computer.

Digital computers use the Binary System (0,1) to represent information in a digital form. This computer is capable of doing mathematical and logical work. For example, a Calculator.

They are somewhat slower than analog computers but more accurate in results. Digital computers can store information.

A digital computer counts and an analog computer measures.

3. Hybrid Computer

These computers have the characteristics of an analog computer and a digital computer. Hybrid Computer is faster than both these types of computers and the results are pure.

In these computers, the digital computer is there to perform a controller and digital work. At the same time, analog computers solve the problem.

They are used in the fields of complex mathematical equations, scientific calculations and defense etc. Petrol Pump Machine, Speedometer etc. are easy examples of Hybrid Computer.

Types of Computers Based on Purpose

5. Super Computer

Super Computer is the fastest and most powerful computer ever made by man.

These computers are very large and expensive in size. They are used by large organizations in research work, weather forecasting, technology etc.

Summit Super Computer is the fastest super computer ever. Which was made in America.

India made its first supercomputer PARAM-8000 in the year 1991. Param Computer was developed by C-DAC, an organization of the Government of India.

After Param, many supercomputers have been built in India. And many are also included in the Top 500 Super Computers.

India’s fastest supercomputers are Pratyush and Mihir.

Modern Computers

Smartphones

Nowadays Cell Phones, which are called Mobile Phones in common language, can also perform many tasks done by computer. You can do Internet Browsing, Games, Documents, Calculation etc work in mobile phone. These are called Smartphones nowadays.
