Daughterboard
Updated: 05/21/2018 by Computer Hope
Alternatively called a piggyback board and daughter card, a daughterboard is an expansion board that connects directly to the motherboard and gives added functionality (e.g., modem). Today, these boards are not found or used in desktop computers. They were replaced with ISA (Industry Standard Architecture) cards, PCI (peripheral component interconnect) cards, and onboard options. However, some laptops still use these boards.
Note
To disable a daughter board, the user must physically remove it from the motherboard.
Note
Some may use the term daughterboard to describe an expansion card.
