                 In the past two decades, computers have reshaped our lives almost everywhere,
                 whether it is at home, work, school, hospital, etc. There has been an enormous

                 increase in the use of computers especially after Covid-19 breakout.
                 A computer can be defined as an electronic device that performs diverse operations
                 with the help of instructions to process the data in order to achieve desired results.

                 A computer  system is made up of a number of electronic  devices which  are
                 connected  together.  It  is made  up  of  both  hardware  and  software.  Hardware
                 refers to the physical components that make up a computer system.

                 Let us explore software in detail.

                     SOFTWARE

                 Software is a set of instructions that makes the computer perform tasks. Software

                 is another term for a computer program. It controls the computer and makes it do
                 useful work. Without software a computer is useless.
                 Software  can  be  classified  into  two  broad  categories:  system software  and
                 application software.


                     SYSTEM SOFTWARE                                                 System Software

                 It is  the most  important  software
                 to operate a computer.  It acts as a                Operating         Programming            Utility
                 mediator between  the computer  and                   System            Software           Software

                 the user to run operations. System software can be classified into three categories:
                 Operating System, Programming Software and Utility Software.

                                                                                            Computer Software      19
