whose destination address is on the same segment as the source address. This confines network traffic to its

respective domain, reducing the overall load on the network.

The Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the

re-transmission rate. No packet loss will occur.

5.5 Auto-Negotiation

The STP ports on the Switch have built-in "Auto-negotiation". This technology automatically sets the best possible

bandwidth when a connection is established with another network device (usually at Power On or Reset). This is

done by detect the modes and speeds at the second of both device is connected and capable of, both 10Base-T

and 100Base-TX devices can connect with the port in either Half- or Full-Duplex mode. 1000Base-T can be only

connected in Full-duplex mode.
