A computer-on-module (COM) is a type of single-board computer (SBC), a subtype of an embedded computer system. Single-board computers ( SBCs) are complete Computers built on a single Circuit board. An embedded system is a special-purpose Computer system designed to perform one or a few dedicated functions often with Real-time computing constraints The COM module is a complete computer built on a single circuit board. A computer is a Machine that manipulates data according to a list of instructions. A printed circuit board, or PCB, is used to mechanically support and electrically connect Electronic components using conductive pathways or traces The design is centered on a single microprocessor with RAM, input/output controllers and all other features needed to be a functional computer on the one board. A microprocessor incorporates most or all of the functions of a Central processing unit (CPU on a single Integrated In Computing, input/output, or I/O, refers to the communication between an Information processing system (such as a Computer) and the outside However, unlike a single-board computer, the COM module will usually lack the standard connectors for any input/output peripherals to be attached directly to the board. Instead, the wiring for these peripherals are bussed out to pin-headers on the board.
The module will usually need to be mounted on a baseboard which breaks the bus out to standard peripheral connectors.
The terms "Computer-on-Module" and "COM" were coined by Venture Development Corporation (Natick, MA, USA) to describe this class of embedded computer boards.
The term became more notable upon industry standardization of the COM Express format. COM Express, a Computer-on-module (COM form factor is a highly integrated and compact PC that can be used in a design application much like an integrated circuit
