Definition:
A switch is a small device that joins multiple computers together
at a low-level network protocol layer. Technically, switches
operate at layer two (Data Link Layer) of the OSI model. |
| |
| Switches look nearly identical to
hubs, but a switch generally contains more "intelligence" (and
a slightly higher price tag) than a hub. Unlike hubs, switches
are capable of inspecting the data packets as they are received,
determining the source and destination device of that packet,
and forwarding that packet appropriately. By delivering messages
only to the connected device that it was intended for, switches
conserve network bandwidth and offer generally better performance
than hubs. |
| |
| Like hubs, switches primarily are
available for Ethernet, come in a range of port configurations
starting with the four- and five-port models, and support 10
Mbps Ethernet, 100 Mbps Ethernet, or both. |
