What is Operating System

Operating System is an interface between the user and the system, by allocated various hardware resources such as memory among various Software and processes.
In addition it also provides GUI interface for users to easily operate upon the system and hardware. It performs job scheduling, system maintenance, which we will discuss in later posts

A Computer system can be roughly divided into 4 parts - Hardware, Operating System, System Software and Application software.
