Any electronic device which is smart and follows our instructions is called computer. The term   “Computer” has been all derived from the Latin word “Computare”. It means to calculate, or to count or to sum up. It also means to think together. Computers can also store data for later uses in appropriate storage devices, and retrieve whenever it is necessary.

There are three types of computer :-

Digital ComputerAnalog ComputerHybrid Computer

Lets study each types of Computer in detail.

  1.  Digital computer

 The Computer which have display are known as digital computer. Some examples of digital                   computers include laptops, desktops, and other electronic devices like smartphones.

Advantages of Digital Computer

  • Digital computers allow users to store a large amount of information.

  • New features can easily be added.

  • Ability to change the program without making any changes in the hardware of the system.

  • The cost of the hardware of digital computers is often less.

  • Systems process data digitally at a very high speed.

  • These types of computer uses error correction codes because of which these systems are very reliable.

2.  Analog Computer

The computer which don’t have display is called Analog Computer. Some examples of analog                 computer are Mobile Phone Network Tower, RADAR, Setup box, Radio Signals, Satellite.

Advantages of Analog Computer

  • These computer allow real-time computation and operations at the same time.

  • Analog computer help perform calculations without using transducers to convert both the inputs and outputs to a digital electronic form.

  • Programmers can also scale the problem for the dynamic range.

3.  Hybrid Computer

The Analog setup which are controlled through digital setup are known as hybrid computer.                Here are some examples of hybrid computer are ATM, Super Computer, Industrial                                      computer.

            Advantages of Hybrid Computer

  • The computing speed of hybrid computers is very high.

  • Help in online data processing.

  • It can manage and solve large equations in real-time.

  • Results are produced quickly and in a more efficient manner.
