BIOS
(Basic Input/Output System)
The Basic Input/Output System (BIOS) is firmware used to perform hardware initialization during the booting process and to provide runtime services for operating systems. BIOS is stored on a chip on the motherboard and is the first software to run when a computer starts.
BIOS performs a Power-On Self-Test (POST) to check hardware components and loads the operating system into memory. Modern systems are increasingly using UEFI (Unified Extensible Firmware Interface) as a replacement for BIOS due to its advanced features, such as faster boot times and support for larger hard drives.
