                 As you know, a computer is an electronic device used in different places for different purposes,
                 such as managing accounts in schools and reading at home. You have also learnt about computer
                 programs and programming in the previous class. In this chapter, you will learn about the different
                 types of computers and computer languages.

                  i +  CATEGORIES OF COMPUTERS

                 Nowadays, different types of computers are used that can be categorised on the basis of their:
                 •  Type
                 •  Purpose

                 •  Size, speed, processing power, and cost

                 Let us learn about these categories in detail.
                 Type

                 On the basis of their type or functioning, computers can be classified into
                 three categories, which are as follows:
                 •   Analog: It refers to a computer that operates by measuring instead
                   of counting. It measures continuously changeable physical quantities
                   like voltage, pressure, water flow, etc. This type of computer generally
                                                                                                 An Analog Computer
                   displays the output in the form of a graph. Examples of analog computers
                   are analog thermometers, speedometers in cars, old radios, etc.
