An operating system is required to to perform a variety of functions. Some of the important functions are given below:
1)job sequencing, 2)error handling, 3)interrupt handling, 4)resource control, 5)multi access, 6)command interpretation, 7)input/ output handling, 8)sheduling, 9)protection, 10)accouting of resources.
an operating system is designed with mechanisms to provide the above given facilities in a computer system. Therefore, it is divided into various functional units so that each given unit can take care of appropriate resources and their functions.
As a resource manager, the operating system performs the following operations:
1)keeps track of the status of each resource.
2)decides which jobs should get the resources and for how much time, according to some policy.
3)allocates the resources to the job decided.
4)after the resource is used by the job for allocated time, frees the resource.
These functions for each of the four resources- memory management functions, processor management functions, devices management functions, program and data management or file management.
MS-DOS Command promt is the third operating system
No. It is easier to alter shell when it is not part of the operating system. Answer: its easier but the real answer is shell is not part of Operating system as it is command prompt use to operate operating system and its part of disk operating system
An operating system that doesn't have a graphical user interface, you have to run it using commands only.
A user communicates with the operating system by using a keyboard. You can also communicate with the operating system by using a mouse.

DOS stands for Disk Operating System. To be useful computers have to have an operating system. The early IBM PC computers used the MS-DOS operating system. A DOS command is an instruction to the DOS operating system. It must be in a specific form. For example, the command DIR told the DOS operating system to list all files. These commands were typed at a place called the DOS command line. There a many such commands.
Command set and command switches. Both are based on the UNIX operating system, so they have the core of the operating system in common.

The CPU needs to understand a command keyed in by a user. The CPU can interpret only binary code, i.e. the code containing 0's and 1's. A command keyed in by user has to be translated to binary code for the CPU to understand it. An operating system performs this task.
