Q18. The operating system is called a resource manager. List four distinct resources of the computer system. What are the general functions that the OS perform for these resources?
Ans. An operating system is an important component of a computer system which controls all other components of the computer system. Major components of a computer system are:
- The Hardware
- The Operating System
- The Application program routines (compiler, linker, database management systems, utility programs)
- The Humanware (users)
Where hardware provides the basic computing resources, the application program routines define the ways in which these resources are used to solve the computing problems of the users and the Operating System controls and coordinates the use of the hardware among the various application programs for the various users.
