Device Firmware
What is BIOS?
BIOS refers to low-level firmware used to initialize hardware and help a computer start up.
What it is
BIOS is associated with system startup and hardware initialization.
Why it matters
It is part of the bridge between physical hardware and the operating system startup process.
How to think about it
It matters because systems need a reliable startup process before the operating system loads.

BIOS in simple terms
BIOS is older system firmware that helps a computer start up by checking hardware and beginning the boot process. It was the standard startup firmware environment on many older PCs before UEFI became more common.
How BIOS works
BIOS runs at startup, initializes key hardware, performs early checks, and hands control to the operating system boot process. It is one of the earliest software layers that runs when a PC powers on.
Why BIOS matters
BIOS matters because it shaped how PCs booted for years and is still relevant when understanding older hardware, compatibility issues, firmware settings, and the evolution from BIOS to UEFI.
Common BIOS misconceptions
- BIOS is not the operating system.
- BIOS is not the same thing as general device firmware.
- Newer systems often use UEFI instead.
