Functions Of Operating System

Functions Of Operating System - Operating System Allows Computer User To Communicate With The Computer. The Following Are The Functions Of Operating System. Start And Shut Down Computer Providing A User Interface Managing Program Managing Memory Co-Ordinating Task And Configuring Devices Monitor Performance Establish An Internet Connection Provide File Management And Other Tools Update Automatically Control A Network Administer Security

When You Start Up The Computer The OS Operating System Will Execute A Series Of Tests To Check The Various Components.If Any Problem Occur It Display Error Message And Such.

An OS Manages Programs An OS Can Be Single Tasking Or Multi Tasking But Most Computer Today Are Multitasking Which Allows Two Or More Programs Or Apps To Reside In Memory At The Same Time.  

An OS Also Manages Memory.

The OS Allocates Or Assign Data An Instructions To An Area Of Memory While They Are Being Processed, Then It Carefully Monitors The Contents Of The Memory. Finally, The OS Releases This Items From Being Monitored In Memory When The Processor No Longer Requires Them. So That The Use Of Computer Or Devices Internal Memory Can Be Optimized.  

Other Than That The OS Also Coordinates Tasks.

A Task Is An Operation The Processor Manages Including Receiving Data From From Input Device, Processing Instructions, Sending Information To An Output Device. And Transfering Items From Storage To Memory And Vice Versa.   Where It Determines The Order In Which Tasks Are Processed.  

Then, The OS Other Function Is Configuring Devices

This Is Possible With The Help Of Device Driver. Each And Every Device Have Its Own Specialized Commands, Thus They Need Their Own Driver.  

Next, The OS Monitors Performance 

A Performance Monitor Is A Program That Assesses And Reports Information, About Various Computers Resources And Devices.  

Besides, An OS Also Establishes Internet Connections

By Providing A Means. Some Connections May Be Configured Automatically As Soon As You Connect To The Internet But Others May Need To Be Set Up Manually.  

Further More, An OS Is Responsible For Updating The Operating System Software.

Many Programs, Including OS Include An Automatic Update Feature That Regularly Provides New Features Or Corrections Of The Programs. So OS Will Automatically Checks If Any Update Are Available And If So, Downloads Them From The Internet And Installs Them In Your Computer.  

In Addition, OS Provides

File, Disk And System Management Tools Such As File Manager, Image Viewer, Search Uninstaller, File Compression And Much More.  

An OS Also Controls Network

Some OS Are Designed To Work With The Server On A Network. Which Allows Multiple Users To Share A Printer, Internet Access, Files And Programs.  

On The Other Hand, Some OS Has Network Features

Built Into Them. In Other Cases, The OS For The Network Is A Set Of Programs That Are Separate From The OS On The Client Computer To Access The Network.

Lastly, An Os Also Administer Security

Most Multi-User OS Allows Each Other To Sign In. Which Is The Process Of Entering A User Name And A Password To Lock An Entire Device Or Computer.   I Hope You Understood The Functions Of Operating System, Share This Post WIth Your Friends So That They Can Also Understand The Functions Of Operating System.       Read the full article
