[purple][b][size=3]Operating System (OS)[/size][/b][/purple][br][br]¶
¶
An operating system is the overall set of instructions that are required for managing¶
and co-ordinating various parts of a computer system.¶
An OS keeps track of where the informations are stored and controls the operation of each ¶
PC component or I/O devices connected to the the computer.[br][br]¶
¶
In short it can be said that the OS is master control program of the computer system.¶
It is responsible for:[br]¶
1:Memory & CPU Management[br]¶
2:Disk Management[br]¶
3:I/O device Management[br]¶
4:User Interface [br]¶

[purple][b][size=2]Memory & CPU Management[/size][/b][/purple][br][br]¶
When any job is performed by computer, OS calls it from the disk and loads it into ¶
computer's memory RAM. However before loading the program OS checks whether sufficient¶
memory is available or not and if available then OS allocates memory for the job.¶
After execution of the job, OS removes the job from the memory so that the freed memory ¶
can be allocated to the next job.¶
CPU processes any job assigned to it. OS handles the problem of assigning various jobs to¶
CPU for processing. This function of OS is known as job scheduling.¶
¶
[purple][b][size=2]Disk Management[/size][/b][/purple][br][br]¶
TheOS helps in storing and retrieving files as and when required. We users need not have to ¶
think of how data is tored or where it is stored in the storage device or where to search for it, ¶
as the OS takes care of all this for us.¶
¶
[purple][b][size=2]I/O Management[/size][/b][/purple][br][br]¶
The computer system consisting of the motherboard is connected to various peripherals. The¶
OS assigns priorities and communicates with these devices.¶
¶
[purple][b][size=2]User Interface[/size][/b][/purple][br][br]¶
The OS helps in bridging the gap between human and the machine with the help of| OS¶
command interpreter. As we type any command on the keyboard and the machines response is ¶
again converted into human understandable form for us.¶
