OPERATING SYSTEM:-

Computer hardware, by itself, is not capable of communicating to you directly. It needs some communicating channels to talk to you, which is provided by the operating system. These programs translate your instructions or questions into the computer language or machine language. The operating system is defined as a program that instructs your PC how to work with its various components.
An operating system is a kind of master control program of the computer. Just as traffic police man controls the vehicular traffic around area,similarly the operating system manages the computer. It helps you manage files and checks various peripheral devices such as printers, monitors etc.
COMPILERS:-
