Backplane vs. Motherboard

Backplanenoun

(electronics) A circuit board that connects several connectors in parallel to each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus.

Backplane

A backplane (or ) is a group of electrical connectors in parallel with each other, so that each pin of each connector is linked to the same relative pin of all the other connectors, forming a computer bus. It is used as a backbone to connect several printed circuit boards together to make up a complete computer system.

Motherboardnoun

(computer hardware) The primary circuit board of a personal computer, containing the circuitry for the central processing unit, keyboard, mouse and monitor, together with slots for other devices.

Motherboardnoun

The board containing the main circuits of an electronic device, especially computers. The term is used primarily in microcomputer literature, where it designates the board containing the main expansion bus, and usually also the cpu. On motherboards designed with an expansion bus, often all of the circuits not contained on an expansion card are on the motherboard.

Motherboardnoun

a printed circuit board containing the principal components of a computer or other device, with connectors for other circuit boards to be slotted into.

Motherboard

A motherboard (also called mainboard, main circuit board, or mobo) is the main printed circuit board (PCB) in general-purpose computers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals.
