Motherboard Components and Architectures

A PC motherboard is a large printed circuit board that is home to many of the essential parts of the computer, including the microprocessor, chipset, cache, memory sockets, expansion bus, parallel and serial ports, mouse and keyboard connectors, and IDE, EIDE or SCSI controllers. The motherboard binds the PC's operational components together. External devices are either connected to or controlled by the devices or controllers on the motherboard.
