                 As you know, a computer is an electronic device used for various tasks, such as managing accounts
                 in schools or reading at home. In the previous class, you learned about computer programs and
                 programming. In this chapter, you’ll discover the different types of computers and computer
                 languages.

                    CATEGORIES OF COMPUTERS

                 The different types of computers are used for various purposes and they 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: This type of computer works by measuring continuously
                    changing physical quantities, such as voltage, pressure, or water flow,
                    rather  than  counting.  It usually shows results as graphs.  Examples
                    include mercury thermometers, car speedometers, older radios etc.



                                           Digital: This type of computer uses binary numbers (0s and 1s) to
                                          generate, process, and display data. It provides more accurate results
                                          compared to analog computers. Modern devices like desktops,
                                          laptops, smartphones, digital watches, digital thermometers, and
                                          electricity meters are all examples of digital computers.
