Updated on:
A printed circuit board that plugs into another circuit board (usually the motherboard). A daughtercard is similar to an expansion board, but it accesses the motherboard components (memory and CPU) directly instead of sending data through the slower expansion bus.

A daughtercard is also called a daughterboard.

See “What You Need to Know About Motherboards” in the Quick Reference section of Webopedia.
