Types of computer

 Types of computer.

There are three types of  computer.

1.Analog computer.

2.Hybrid computer.

3.Digital  computer.

Analog computer.

      The term analog is taken from the word analogous  which means similar.Analog represent data continuously.Analog computers are commonly used for scientific and engineering problems, particularly in chemical industries, electric power plants.Transmission means of transmission of analog signals without regard to their content.                                                                                                   

 Hybrid computer.

   Hybrid computer uses analog to digital conversion and digital to analog conversion, and may input or output either analog or digital data.Hybrid computer is combination of analog and digital computer system.

Digital computer.

Digital computer represent data discretely, as 0s or 1s.Digital computer are computer  that  specialize in counting. Unlike the analog computer which receives data in a continuously form, the digital computer form,the digital computer handle values  that are  in a discrete number.

             Define computer

In basic term, a computer is an  electronic device  that process data, converting  it into information  that is useful to a people.

In the simplest word we can say any device which can computer or calculate is also known as computer.      

  A computer is an electronic device that accept data in one from and process it to produce data  in other form.

A computer is a machine  which works under  the control  of stored program,automatically accept storing processing dating to produce information which is the result of that processing.
