The motherboard is like the nervous system of your device. Without a motherboard, your device is just a useless hunk of electronics!

Motherboards are generally very easy to identify, because they're one of the largest components in your device. Many of the other components inside your device connect to the motherboard.

"Motherboard" is a generic name for the largest circuit board in a device. Apple calls their motherboards "Logic boards." This is brand-specific nomenclature. So unless you have an Apple device, you are working with a "motherboard."
