TYPES OF BOARD

Motherboard

Motherboard is a resin or plastic board, which contains all the chips, which form the main electronic circuits of the computer. That is the microprocessor, ROM memory chips, such as the BIOS chips, RAM memory chips, the clock, and IC's that connect the CPU to the bus. The motherboard also contains the parallel conducting paths (bus), which interconnect the chip, as well as provides connection to the outside.

These paths are printed onto the motherboard as parallel lines of conductor which makes PRINTED CIRCUIT (PC) board.

Daughter board

Daughter boards are interface cards or PC boards that plug into the motherboard to control peripheral devices. The main interface boards are the video card, sound card and modem or network card. Older computers may have a controller card although most systems have this option included on motherboard. Other cards may be scanner cards, interface cards etc.
