in the subnet address. Refer to Installing and Administering LAN/9000 Software for detailed information about subnet masks.

Switch: A network interconnection device that allows multiple connected senders and receivers to communicate simultaneously in contrast to a hub (repeater) where only one device can send at a time. Some switches have ﬁxed port speeds (10 or 100 Mbps) while others allow port speeds to be conﬁgured or autonegotiated.

T

Topology: The physical and logical geometry governing placement of nodes in a computer network. Also, the layout of the transmission medium for a network.

U

Unshielded Twisted Pair: A data cable type consisting of pairs of wires twisted together without an electrically shielding jacket.
