Operating System Overview

introduction:

Here we have alot of information about operating system overview, so you need to read all information to guide you to understand basic ideas of operating system.

Operating System (OS), in computer science, the basic software that controls a computer.

- The operating system has three major functions:

- It coordinates and manipulates computer hardware, such as computer memory, printers, disks, keyboard, mouse, and monitor.

            - It organizes files on a variety of storage media, such as floppy disk, hard drive, compact disc, digital video disc, and tape. 


         -It manages hardware errors and

           the loss of data.

 

Operating systems control different computer processes, such as running a spreadsheet program or accessing information from the computer's memory.

One important process is interpreting commands, enabling the user to communicate with the computer. Some command interpreters are text oriented, requiring commands to be typed in or to be selected via function keys on a keyboard.

Other command interpreters use graphics and let the user communicate by pointing and clicking on an icon, an on-screen picture that represents a specific command.

Beginners generally find graphically oriented interpreters easier to use, but many experienced computer users prefer text-oriented command interpreters.
