What is an operating system?
A operating system Where OS (Operating System) is a program package essential components that enable a computer or PC to function. It acts as the link between the user, software, and hardware components such as the processor, memory, hard drive, and USB drives.

When you press the ignition switch of a computer, a process called priming " Where " boot » begins. The word boot comes from the English expression “bootstrap,” which means “to start up on your own.” First, the BIOS (UEFI on recent machines) is activated. This is a small program stored on the motherboard that launches the start-up process. This BIOS checks that the essential components are present and functional: processor, memory, storage, etc. It then detects a hard disk, USB key or external drive to load the operating system (OS). Next, it detects a hard disk, USB key or external drive in order to load the operating system (OS). This is when the system, for example Windowsstarts up.
