STP (Shielded Twisted Pair). A type of cable that consists of two shielded wires
twisted around each other. It is used extensively for local area networks and
telephone connections.
Switch. A switch is essentially an intelligent hub. When a packet arrives at the
switch, it looks at the packet, determines which computer the packet is directed
to, and forwards the packet to that computer. By contrast, a hub regenerates the
packet and broadcasts it to every computer connected through it.
TCP/IP (transmission control protocol/Internet protocol). A networking
protocol that provides communication across interconnected networks, between
computers with diverse hardware architectures and various operating systems.
TCP and IP are only two protocols in the family of Internet protocols. However,
TCP/IP is used to denote the family of common Internet protocols.
Telnet. Terminal emulation program for TCP/IP networks that runs on your
computer and connects your PC to a server on the network.
Traffic. A measure of the quantity of data transferred from one computer to
another computer per unit of time. Traffic is normally measured in megabytes.
Upload. To transmit files from your computer to another through a network.
UTP (Unshielded Twisted Pair). A type of cable that consists of two unshielded
wires twisted around each other. It is used extensively for local area networks and
telephone connections.
WLAN (wireless local area network). A type of local area network that uses
high-frequency radio waves instead of wires to communicate.
