What is Operating System?

                                     Operating System

  We all know that there are many hardware’s and software’s which  are attached to  a system. So for performing any operations both software and hardware are compulsory. So For exchanging information between software and hardware  operating system is used. Operating system is that which communicate  with  software and  hardware. The software is the non-touchable part of the system, and  software’s are just used for making an application but hardware’s  are used for performing an operation . For example if we want to perform a activity of playing a song then media player is an software and using mouse is an hardware , but how the system knows what to do when mouse moves on the screen and when the mouse select a song on the system so that operating system is necessary which interact between or which communicates with the hardware and the software. For better understanding you can see the working of the operating system.

so we can say that the operating system have the following characteristics :-

1) Operating System is a Collection of Programs which provides platform for Execution of other Programs.

2) Operating System  Controls  all the Input and Output Devices those are connected to the System.

3) Operating System is the platform on which we Run all the Application Software’s.

4) Operating System Provides Scheduling to the Various Processes Means Allocates the Memory to various Process those Wants to Execute.

5) Operating System provides medium to exchange information between the user and the System.

6) Operating System is Stored into   the Basic Input and Output System means when a user Starts his System then this will Read all the instructions those are Necessary for Executing the System Means for Running the Operating System, Operating System Must be Loaded into the computer  For this, we will use the Floppy or Hard Disks Which Stores the Operating System.
