                 As you know, a computer is an electronic device used in different places for different purposes,
                 such as managing accounts in banks, teaching in schools and reading at home. You have also
                 learnt about computer programs and programming in the previous classes. 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 the type or functioning of computers, they can be classified into three categories,
                 which are as follows:
                 •   Analog: It refers to a type of computing machine that operates by
                   measuring quantities instead of counting. It measures continuously
                   changeable  physical  quantities  like  voltage,  pressure,  water  flow,
                   etc. This type of device generally displays the output in the form of
                   a graph. Examples of analog computers are analog thermometers,
                   speedometers in cars, old radios, etc.
