, • The BIOS is a small program built into your
computer's motherboard. When you turn o
your computer, the BIOS helps start
everything up. It checks if the computer’s
parts, like the processor and memory, are
working properly. Then, it gets everything
ready so the operating system (like Window
What is BIOS ? or macOS) can load and run.
• In other words, the BIOS is like a "starter" t
makes sure all the computer's parts are re
before the main software (the operating
system) takes over. Without it, the comput
wouldn’t be able to start.
