A motherboard is the main circuit board inside a computer that connects and allows communication between all the major parts, like the processor, memory, and storage. It acts as the central backbone of the computer’s hardware.
Formed in English from *mother* and *board*, using *mother* in the sense of “main” or “source of others,” as in *mother ship*. The term became common with the rise of personal computers in the late 20th century.
