Motherboard
The motherboard is the main circuit board of a computer that contains the slots and sockets which interfaces, drives and peripheral devices plug into. On most PCs, memory can be directly added to the motherboard and upgrade to a faster PC by replacing the CPU. |
| A loaded motherboard contains processor, fans, cache, memory, and connectors for I/O devices such as networks and disks. Typical PCI (Peripheral Component Interconnect) cards include: network cards, sound cards, modems, and disk controllers. |
