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, 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.
