The Operating System

The Operating System
The operating system (OS) consists of the master of programs that manage the basic operations of the computer.

These programs provide the control and use of hardware resources, including disk space, memory, CPU time allocation, and peripheral devices.

They are also the interface between computer hardware and application programs, allowing end users can concentrate on their own tasks or application rather than on the complexities of managing the computer.

To be more specific, the operating system is used to control the hardware memory, schedule the execution of programs, and schedule input output traffic between the CPU and other devices.

A good operating system, can dramatically improve the effectiveness and the efficiency of program execution performance.

Many different operating systems are available for computers.

Some operating systems are designed for a microcomputer single user environment, and others are for multiple users.

The complexity of operating system is much higher in a multiple user operating system due to the management of computer memory and CPU time shared by many users.

Today, many computers use what is called an operating environment, which provides end users with a user friendly interface to use.

Some operating systems have a graphical user interface that provide visual clues such as icons and objects the help the users.

Each icon represents a folder, an application package, or file. By clicking icons, users can open a folder or use an application package.
