The basic concept of the operating system

 Objectives of the operating system

What is the operating system? Operating System is basically a system software. That The software combines different parts of the computer, using computer capabilities Manage application software. The operating system is such a system Software that controls the computer program execution and scheduling, debugging, input Output rules, accounting, compilation, memory management, data management, and conservation etc. Works.

Operating system history

Initially, the operating system was created for the mainframe computer in 1951. The operating system is based on IBM’s General Meteor Research Laboratory, Was made for the corporation. The operating system on personal computer or microcomputer Used to be used since 1971. The operating system name was CPM.

 Repeat the widely used operating systems:

  1. MS-DOS, PC-DOS.
  2. MS Windows 95.98,2000 ME, XP.
  3. Unix.
  4. Linux.
  5. Xenix.
  6. Mac OS.
  7. Solaris.
  8. OS / 2 Warp.
  9. MS Windows NT.
  10. MS Windows Vista.

Operations of the Operating System

( Importance of Operating System )

The operating system creates life on the computer. It’s a bridge between the computer and the user Make the bid. By joining the computer with the operating system It is able to run applications between the applications. So without the operating system The computer is nothing but a metal. The importance of the operating system is shown below.

Functions of an Operating System.

Depending on the size, structure, and priority of the computer, the size of the operating system, size, or larger And the scope of work is less or more. Under the operating system’s RAW works in the picture below Presented

User Interface

User Interface is a part of the operating system that is compatible with the user’s software Provide assistance in getting involved in coordination, coordination, management, and direction. Moreover, software controls And he started doing good work and doing good work. An operating system is usually three Type of user interface can be seen. Namely- command-driven, menu-driven, and graphical user Interface

Resource Management

The operating system activates the computer and uses it. It’s a variety of computers A resource such as input and output devices (keyboard, mouse, monitor, PCC / hard disk drive, printer, Scanners, etc.) and the control of other nymphs, it observes and coordinates. Moreover, the management of magnetization increases the computer’s accuracy.


 The operating system protects the computer’s precursors from unwanted users. It’s data And helps to steal information theft.

Task Management

 The operating system’s task management refers to the city of love, analysis and batch processing Do it. In this, the CPU’s time slice is divided into various tasks and controls interrupts. So that all the work is done properly.

 File Management

Operating system file management, such as creating files, file extract, access, copy, move, save Etc. Besides, fat and love manipulation, such as data transmission, transfer, and conservation work.


The operating system allows users to access various types of facilities such as file defragmentation, data compression, Backups, Data Recovery, Anti Virus Utilities etc.
