The motherboard is connected to other components in the computer, such as the hard drive, optical drive, and video card, through expansion slots and connectors.
A daughterboard is a smaller circuit board that is connected to a larger circuit board, such as a motherboard. Daughterboards are often used to add additional features to a computer, such as more memory or storage space.
A fatherboard is not a real term. It is a made-up word that is sometimes used to refer to a motherboard.
A breadboard is a temporary circuit board that is used to prototype electronic circuits. Breadboards are made up of a grid of holes that can be used to connect electronic components.
