What is a command shell?

What will be an ideal response?

The command shell is a separate software program that provides direct communication between you and the operating system. When you enter a command, the command interpreter executes it, requests that the operating system perform the task for you, and displays text output on the screen. The command shell of the Windows server operating system uses the command interpreter CMD.EXE, which translates user input into a form that the operating system understands.
