Introduction:-

    An operating system is a program that manages the computer hardware. It also provides a basis for application programs and acts as an intermediary between a user of a computer and the computer hardware. Mainframe operating system are designed to optimize utilization of hardware.

Personal computer (PC) operating system support complex game, business applications and everything in between. Handheld computer operating system (OS) are designed to provide an environment in which a user can easily interface with the computer to execute programs. Thus, some operating systems are designed to be convenient, other to be efficient and other some combination of the two.

Operating System (OS):-

    An operating system is an important part of almost every computer system. A computer system can be divided roughly into four components: the hardware, the operating system, the application programs and the users.

"Operating system is a software program with the help of which we can understand or explain computer hardware and can run computer software. Without operating system no work can be done in computer."

The definition of an operating system since 1960 was "the operating system that controls computer software and hardware." But, today a good definition is needed on the basis of microcode.

Operating System uses by:

    The Central Processing Unit (CPU), the memory and the input/output devices, provide the basic computing resources. The application programs such as word processor, spreadsheets, compilers and web browsers define the way in which these resources are used to solve the computing problems of the users. The operating system controls and coordinates the use of the hardware among the various application programs for the various users.

The components of a computer system are its hardware, software and data. The operating system provides the means for the proper use of these resources in the operation of the computer system. It simply provides an environment within which other programs can do useful work. Operating system can be explored from two viewpoints: the user and the system.
