On-board

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, or video card 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.
