Output

                  The result produced from processing data and instructions is called output. Output
                  displayed on a monitor is referred to as a soft copy, while a printed version of this
                  output on paper is known as a hard copy.


                     TYPES OF COMPUTERS

                  All types of computers come with a CPU, a keyboard, and a screen for displaying

                  output. However, they differ in size, cost, and speed. Let’s take a closer look at
                  these variations.

                  Microcomputers

                  These computers are designed for use by one person at a time. Desktops, laptops, tablets,
                  and smartphones are known as microcomputers or personal computers (PCs).

                  Minicomputers

                  These computers  are  small, general-purpose  machines
                  designed to support multiple users simultaneously.

                  They are used for scientific and engineering computations,
                  business transaction processing, file handling, and database

                  management.

                                                                Mainframe Computers


                                                                These computers are extremely large,  fast,
                                                                and  powerful.  Some mainframe computers
                                                                are  so massive  that they occupy the entire

                                                                space of a room.
                                                                They are used by large organisations where
                                                                significant amounts of data  are  processed,

                           Mainframe Computers                  such as banks.
