All computers require an operating system (OS). Operating systems are found on every device that contains a microchip—from cellular phones and video game consoles to tablets and web servers. The operating system acts as an intermediary between the user, various software programs, and hardware.
The operating system is the most important software on your device. An operating system can be defined as a program that manages hardware resources and provides common services for software. It is the framework that allows you to communicate with your computer hardware in an interactive way.
