What is an Operating System?
The Operating System (OS) is an application that functions in the role of an intermediary between parts and its user. Each computer must be equipped with at the very least one operating system in order for other applications. Applications such as Browsers, MS Office, Notepad Games and so on. require an environment in order to run and complete their tasks.
The OS lets you communicate with the computer , without having to know it's own language. It is impossible for a user to utilize any mobile or desktop computer without OS.

History Of OS
Operating systems were invented in the 1950s to handle tape storage
The General Motors Research Lab implemented the first OS in the 1950s in the beginning of their IBM 701
In the middle of the 1960s operating systems began to utilize disks

Real-time OS
A real-time operating system's time-frame for processing and responding to inputs is extremely short. Example: Military Software Systems, Space Software Systems are the Real time OS example.
Distributed Operating System
Distributed systems employ a variety of processors that are located in various machines to provide extremely efficient computation to their users.
Network Operating System
Network Operating System runs on the server. It is able to help manage user, data, groups, secure applications as well as other functions of networking.
Mobile OS
The mobile operating system is OS, which is designed to run on tablets, smartphones and wearable devices.
