          An operating system acts as an intermediary
          between the user of a computer and computer 
          hardware. The purpose of an operating system
          is to provide an environment in which a user
          can execute programs in a convenient and 
          efficient manner. An operating system is 
          software that manages the computer hardware. 
          The hardware must provide appropriate mechanisms
          to ensure the correct operation of the computer 
          system and to prevent user programs from 
          interfering with the proper operation of the system.
