Operating system

The operating system (OS) is specialized computer software that allocates memory and manages system resources. When a computer is turned on, the OS is loaded into memory and works as an abstraction layer between the physical hardware and the software. While the Operating system doesn't perform a specific function it helps other programs run smoothly and efficiently. In this course you will learn about the structure and functionality of operating systems.

The operating system is an integral layer in the modern computer.
