a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted. A bus is the path through which a device sends its data so that it can communicate with the CPU and or other devices. There are traditionally three different types of buses found on a mother board which are the front side bus (F.S.B) which can be explained as being the interface between the cpu & motherboard, Specifically the north bridge/ memory controller hub. The second bus typically found is called a Intel GTL which can be explained as the single connection to the north bridge shared between all cpu`s. The third most typical bus found in a motherboard is DDR-SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory). This upcoming replacement for SDRAM is basically the same product, but it operates twice per clock cycle. DDR-SDRAM is only about 10 to 20 percent more expensive than traditional SDRAM and provides better performance than single-channel RDRAM. A port expander can be any device to which one existing or onboard port becomes two or more, An advantage to this is the ability to allow more devices of a particular port. The internal expander has a connection inside the computer typically on the motherboard. An external device plugs into the existing port and then has multiple places to connect. When not part of a computer system, these devices are commonly known as splitters. There are many advantages and disadvantages to using port expanders, for example The main advantage to using a port expander is that you can get more available ports to use and plug things into. The main disadvantage to using port expanders are the original port can only handle so much bandwidth, so evidentially your limited.
