Computer module

This article is about computer hardware modules. For computer software and hardware modules, see Module (disambiguation).

Not to be confused with Computer-on-module.

DEC's original products were individual modules, like these System Building Blocks 1103 hex-inverter cards (both sides).

CDC used much smaller modules in their early computers.

A computer module is a selection of independent electronic circuits packaged onto a circuit board to provide a basic function within a computer. An example might be an inverter or flip-flop, which would require two or more transistors and a small number of additional supporting devices. Modules would be inserted into a chassis and then wired together to produce a larger logic unit, like an adder.
