What is Operating System

What is Operating System 


           The operating system is a system software that organizes computer systems' hardware resources, such as memory, processor and input-output devices. The operating system is a system of systematic frozen software that controls the transmission of data and instructions. Operating system, takes account of each resource status of computer systems -jokha and who when it takes decisions and how will control the computer resources for a while. There are mainly four components of a computer system -


* Hardware
* Operating System
* Application Program
* Users


The operating system requires 
operating system hardware and software to bridge the bridge. Computer has no existence in itself. It is a group of hardware such as key board, monitor, CPU etc. The operating system establishes a connection between all the hardware. The operating system is the NHS no reason to keep track of different parts of a computer that the same user, the user can go without all your work stress it does not share system resources and organize. is.

There are many other useful sections of the operating system, many of which are delivered by a central processor. For example, printing is done, then the central processor gives the necessary order and leaves the work on the operating system. And he himself starts doing the next job. In addition to renaming the files, changing the directory of the directory, changing the directory, etc. are done by the operating system. Here are the following functions

: - 1) File system: -
Creating files, erasing and moving files from one location to another. Organizing the file directory.

2) Process: - 
Distribute the program and data in memory and start the process, copy of the user intermediary file, instructions for directory, etc., graphical desktops etc.

3) Input / output: - 
Monitor, printer,

It can be said that the system software (System Software) designed to manage hardware resources, such as Memory, Processor, and Input-Output Divices ) Is the operating system. It is a set of systematic frozen softwares that control data and instructions. The accounting system of each resource in the computer maintains the operating system, the operating system decides who will have control over the computer resources for whom, when and for how long.
Why Operating System Is Important

As mentioned above, the operating system acts as a medium between us and the computer. Apart from this, it also acts as a bridge between hardwares and softwares. Without the operating system, the computer itself has no existence. If there is no operating system, then the computer will never be able to establish a connection between its hardware such as a keyboard, monitor, CPU etc. Operating system protects a computer user from the point of view that he keeps information about all the components of the computer.
Operating Systems Functions
Operating system does a number of useful functions, some of which are given below:
  • File System - Create, delete, and move files from one place to another and arrange the file directory.
  • Processing - Sharing programs and data in memory, starting process and running properly.
  • Input / output - Mediate between CPU and Monitor, Printer, Disk, etc.
Types of Operating Systems
Though different operating systems were created in different periods, but the list of popular operating systems used primarily is given below:
  • Linux
  • MacOS
  • MS DOS
  • IBM OS / 2
  • Unix
  • Windows CE
