                     To Sum Up

                           A computer system  is  a collection of hardware  and software  components,
                         designed to provide an effective tool for computation.
                           A computer needs instructions to do anything. These step-wise instructions are
                         called software.

                          The operating system serves as an interface between the user and the hardware.
                           A language translator helps the computer understand and convert instructions
                         from programming languages into machine language, which the computer
                         can run.
                           Backup Utility is used to create copies of important files so you have them in
                         case of an emergency.

                           The software that are designed to perform some specific type of jobs on a
                         computer are called application software.
                           System software  is pre-installed while users can  install and  uninstall the
                         application software as per need.
                           Operation Support System  is  used by Telecommunication Service Providers
                         (TSP)  for  monitoring,  controlling,  analysing  and  managing  a  computer  or
                         telephone network system.
