What are Types of Computer? | Introduction to Computer

In this Article we will discuss about introduction of computer and types of computer. Today, you can find Computer almost everywhere. Microwave ovens, Automobiles, thermostats and even wristwatches contain computer chips. In fact, Computer are so common in modern society that everyone is affected by Computer technology to some extent.

Introduction to Computer

A computer is an electronic device that processes data and convert it into information. Computers run programs, which processes data and perform tasks based on the instructions contained in the programs. Because a computer program can evaluate data and then based on those evolution, results are generated which can be used a large number of applications. Computer can process data with little assistance. Some examples for computer applications are:

  • Controlling space fight
  • Landing airplanes
  • Tracking inventory
  • Painting books
  • Turning on lights at a specified time
  • Checking out groceries at the checkout counter

In this article, we will explore the history of computer and define the difference type of computer available today. Also, the impact of computer on society will be discussed along with the introduction to programming languages.

What are the types of computers?

There are three types of computer

  • Analog Computer
  • Digital Computer
  • Hybrid Computer

 Analog computer

Analog computer use electronic or mechanical phenomena to model the problem being solved by using one kind of physical quantity to represent another.

The Analog computer excels is solving dynamic problems and simulating complex physical systems. It has no way for man-machine interaction, recording and graphic display. High-speed computing elements, used to simulated mathematical functions, physical systems, and dynamic processes, are arranged in as much the same pattern as the physical system they represent.Early special-purpose Analog computer were the slide rule, the curve meter and plain meter, and the harmonic analyzer. In World War ¡¡, Analog computing mechanisms were of the great importance for gunfire control on warships. General-purpose Analog computers were first built in 1930s.

Digital computer

Digital computer process data in numerical from using digital circuits. The digital computers perform logic operations and arithmetic with discrete values. Digital computers are specially design for solving algebraic expression and even better at manipulating numbers. Digital Computers are unbeatable for high speed reliable results in arithmetic operations, data storage and documentation. It can tables perform only one calculation at the time.

The result can be obtained in a variety of forms, such as painted tables magnetic tape, and the familiar purchased cards. While properly used in high-accuracy, high-volumes numerical calculations, the digital computers are extremely good.

In early 1940s, Aiken built the first general-purpose digital computer is called

MARK-1, with the invention of digital computers, a new age of computing started . Today digital computer are widely being used in business, educational institutes, hospitals etc. for various purposes. Examples of digital computers are IBM  PC, Apple’s Macintosh computer etc.

Hybrid Computer

Hybrid Computer are the combination of Analog and digital computers. Hybrid Computer use analogue-to-digital conversion

and digital-to-analogue conversion, and May input and output either Analog and digital data. Dynamic problems that once took too long or were too difficult to handle can be solved in a reasonable period of the time. Hybrid Computers can create high accurate and reliable results. These type on computers are used in robotics, medical labs etc.
