What is Operating System 

The operating system is an interface between a user and the computer hardware. The Computer cannot understand the human output language as it works on binaries i.e. 0 and 1. Also, it is very tough for humans to understand the binary language, in such a case we need an interface that can translate the human language to hardware and vice-versa for effective communication.
