The objectives of an operating system are :
- Providing the ‘user-friendly’ interface so that the user need not bother about the underlying hard-ware. The commands given by user in an natural language are interpreted by the operating system, which in turn uses the hardware to get the required task done.
- Creating an environment for other programs to be executed on the CPU, and allocating the resources to the executing program as and when required.
- Harnessing the full power of the machine so that user can make the best possible use of the hardware for his or her application needs.
