BIOS refers to software that is used to initialize hardware and start your operating system. Before the loading of the OS, it handles required startup instructions.
The BIOS (Basic Input/Output System) is firmware built into a computer’s motherboard that starts up the system. When you power on the PC, the BIOS performs hardware checks, initializes components, and loads the operating system into memory. It also lets users configure hardware settings like boot order and system time.
