This document discusses the components and functions of a motherboard. It begins by defining a motherboard as the main circuit board that forms the foundation for major computer components. The document then lists parts of an ATX motherboard including the power supply connector, CPU, AGP slot, VGA port, and audio section. It also presents true/false statements about the CMOS backup battery, PCI and AGP architectures, the CPU's role, the northbridge chipset, and uses of the parallel port. Reference materials on computer hardware servicing are also listed.
