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


                        COMPUTER CATEGORIES

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

                    Type

                    Size, speed, processing power and price.

                 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 Computer refers to a computer that operates by measuring
                    instead of counting. It measures the continuously changeable physical
                    quantities like voltage, pressure, water flow, etc. Examples of analog
                    computers are mercury thermometer, speedometer in cars, old radio,
                    etc.
                                                                                                  Analog Computer
                                        Digital Computer refers to a computer that uses
                                        digits (binary numbers 0’s, and 1’s) to generate, process and display data.

                                        All the modern computers that currently we use like Desktop, Laptop, and
                                        smartphone are examples of the digital computers. Some other examples
                                        of the digital computers are digital watch, digital thermometer, electricity
                                        meter, etc.
