An operating system is program that manages the computer hardware. It also provides a basic for application programs and acts as an intermediary between the compute user and the computer hardware . An amazing aspect of operating system is how varied they are in accomplishing these tasks. Mainframe operating systems are designed primarily to optimize utilization of hardware . Personal computer (PC) operating systems support complex games, business applications, and everything in between . Operating systems for handheld computer computers 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 , others to be efficient , and others some combination of the two key.
Before we can explore the details of computer system operation , we need to know something about system structure . We begin by discussing the basic functions of system startup , I/O , and storage . We also describe the basic computer architecture that makes it possible to write a functional operating system .
Because an operating system is large and complex , it must be created price by piece by piece. Each of these pieces should be a well-delineated portion of the system , with carefully defined inputs, outputs, and functions . In this article , we provide a general overview of major components of an operating system .
ARTICLE OBJECTIVES :-
- To provide a grand tour of the major components of operating systems.
- To describe the basic organization of the computer systems.
- An operating system is a master software .
