It performs basic tasks, such as booting the system, recognizing
                  input, sending output, keeping track of the location of files and
                  directories  on  the  disc, controlling  peripheral  devices such as
                  disc drives, printers, etc.

                  The operating  system  sets the standard  for the application
                  programs  that  run  on  the  computer.  It  acts  as a  ‘messenger’
                  between the computer hardware and the application programs by ensuring or by establishing
                  a connection between the application and the hardware device. Some of the most commonly
                  known operating systems are Microsoft Windows, Apple MacOS, and Linux.

                   i +  WHY DO WE NEED AN OPERATING SYSTEM?

                  Without an operating system, a computer cannot work and a user will not be able to use the
                  programs because the operating system controls and coordinates the activities of software and

                  hardware as well. The operating system acts as an interface between the computer and the user.
                  It also helps a user communicate with the computer and vice-versa. It communicates with the
                  various parts of the computer so that tasks can be performed effectively and without any delay.

                   i +  FUNCTIONS OF AN OPERATING SYSTEM

                  As we switch on the computer, the work of the operating
                  system starts. After booting, the operating system gets
                  loaded into the memory of the computer system. Once

                  the operating system has been successfully loaded into
                  the memory, it controls and operates all the jobs of he
                  computer.
                  An operating system performs various functions. Some

                  of them are:
                  •  Arranging  Files  and Folders: An
                                                                       Info Byte
                     operating system helps arrange the files
                     and  folders  stored  on  the  hard  disk.        The process of loading an operating system
                     It performs  the  function of retrieving,         is called booting the system.
                     storing, renaming and protecting files. It
                     also keeps track of information about when a file is created, copied, and modified.
