What is BIOS?

BIOS is like the first friend who wakes you up every morning and helps you get ready for school.

Imagine your computer is a robot that needs to know how to turn on and start working. When you press the power button, the BIOS is the first thing that starts up, kind of like a robot teacher who tells the robot what to do next.

How BIOS Works

Think of the BIOS as a special instruction book that comes with your computer. It has all the important rules and steps for turning on the computer, checking if everything is working, and then starting up the operating system, like Windows or macOS.

Every time you turn on your computer, the BIOS goes through its list of tasks: it checks the keyboard, the screen, the memory, and even the hard drive. Once it's sure everything is okay, it starts the operating system so you can use your computer.

BIOS doesn’t change much, it’s like a reliable friend who always knows the best way to start your day.
