Q. What are the three major purposes of an operating system?

Answer:

  • To offers an environment for a computer user to execute programs on computer hardware in a convenient and efficient manner.
  • To allocate the part resources of the computer as needed to solve the problem given. The allocation process must be as fair and efficient as possible.
  • Like a control program it serves two major functions: (1) regulation of the execution of user programs to prevent errors and improper use of the computer and (2) management of the operation as well as control of I/O devices.
