Alternatively referred to as integrated, on-board is a term used to describe a hardware component that is located on a circuit board. On-board is commonly used to refer to a component, such as a sound card, network card (LAN), video card, or WLAN that is integrated onto the motherboard. Unlike expansion cards, users cannot remove these components from their computer; however, they can be disabled through software or CMOS setup or are automatically disabled when an expansion card is added to the computer.
Where are the connections for on-board devices?
On-board devices including the sound card, video card, and the network card are all on the motherboard.
