Operating system taking charge on PCs processes.

An operating system or an OS is a program that runs and controls all the functionalities of a computer. It is the main thing that makes a computer work and basically its main purpose is to really make the machine work and run as what it is designed for. This is the very first program that starts when a computer boots to prepare all devices attached to the computer for use.

Without it actually, a computer is useless because there is nothing that will instruct the computer on what to do. Without it, no drivers will be loaded for the attached devices so a user can use it. Without it, you can not use and install any software. It is the base program needed to install other applications or software. To make it simple, it is the principal program that controls and manages all the mechanisms, devices, and overall functions of a computer.
