Function of operating system

An operating system performs the following functions. 

1. Processor Management
2. Memory Management
3. Input/ Output Management
4. Fill Management
5. Scheduling
6. Time-sharing
7. Securing Management

Processor Management:- 

    The Operating system assigns processors ( if a computer has more than one processor) to the different tasks that must be performed by the computer system. 

Memory Management:- 

    It (OS) allocates the main memory and secondary memory to the system programs, user programs, and data.  

Input / Output Management:-

    It carries out the input/output management and co-ordinates and assigns different input and output devices.

Fill management:- 

    It manages files on various storage devices and the transfer of these files from one storage device to another. it also allows all files to be easily changed and modified through the use of text edition some other file manipulation software packages. 

Scheduling:-

    It establishes and enforces the job priority That is, it determines and maintains the order in which jobs are to be executed in the computer systems. 

Time-sharing:-

    It Co-ordinates and assigns compilers, assemblers, utility programs, and other software packages to various users working on the computer system.

Security Management:- 

    It establishes data security and integrity. That is, it keeps different programs and data I such a manner that they do not interfere with each other Moreover, it also protects data form being destroyed by the wrong user. 

   It produce dumps, traces, error messages, and other debugging and error-detecting codes. 

   It maintains internal time clock and log of system usages for all there users.

   it facilitates easy communication between the computer system and the computer operator ( human). 

The main functions of an operating system, in short, can be categorized as follows.
