Have you ever wondered how a computer knows what to do when you press the power button? That’s where the BIOS comes in! BIOS stands for Basic Input/Output System. It’s a special kind of software that lives in a chip on your computer’s motherboard. When you turn on your computer, the BIOS is the first thing that wakes up and starts working.
The BIOS does a quick check to make sure everything in the computer is working correctly. It checks the memory, the keyboard, the hard drive, and other important parts. If everything is okay, the BIOS then tells the computer to start loading the operating system, like Windows or macOS. This is how your computer knows how to boot up and get ready for you to use.
But BIOS isn’t just about starting up the computer. It also helps your computer manage data between the operating system and the attached devices, like printers, mice, and keyboards. It’s like a translator that helps your computer’s hardware and software talk to each other. And if you ever need to change certain settings on your computer, like which device to boot from, you can access the BIOS by pressing a special key (like F2 or Delete) when your computer is starting up.
