BIOS (Basic Input/Output System)

BIOS, or Basic Input/Output System, is a firmware embedded on a computer's motherboard that initializes hardware during the startup process. It acts as a bridge between the computer's operating system and its hardware components. When you power on your computer, the BIOS checks for essential hardware like the processor and memory, then loads the operating system from your hard drive. It also allows users to configure settings for hardware, boot preferences, and more. Essentially, BIOS is crucial for ensuring that everything starts and works properly when you turn on your computer.
