    Accuracy: It  performs  calculations  without  making

                                                         any mistake. However, we can get incorrect output if

                                                         inaccurate data is fed into the computer.

                      Versatility:  It  performs  various  types  of  tasks  at  the
                      same time.

                                                            Memory: It stores  huge  amounts  of data  and

                                                            information that can be retrieved quickly and easily
                                                            when needed.

                                WORKING OF A COMPUTER

                      As we have discussed earlier, a computer can do a lot of things. Let us understand

                      how a computer works.

                      A computer works in three steps: Input                Process       Output (IPO). This is also
                      called the IPO cycle.

                                        Input                     Process                      Output

                      INPUT

                      We enter data and instructions into the computer which is called input. The devices
                      which are used to send input to a computer are called input devices.

                      PROCESS

                      A computer works on data (input) to produce meaningful information with the help of
                      processing device known as the CPU (Central Processing Unit). This conversion of
                      data into information is called processing. CPU is also called the brain of a computer.
