Instant EtherFast® Series

NIC (Network Interface Card) - A board installed in a computer system, usu- ally a PC, to provide network communication capabilities to and from that com- puter system. Also called an adapter.

Packet - A unit of data routed between an origin and a destination in a network.

Port - A pathway into and out of the computer or a network device such as a switch or router. For example, the serial and parallel ports on a personal com- puter are external sockets for plugging in communications lines, modems and printers.

RJ-45(Registered Jack-45) - A connector similar to a telephone connector that holds up to eight wires, used for connecting Ethernet devices.

STP - (Shielded Twisted Pair) Telephone wire that is wrapped in a metal sheath to eliminate external interference.

TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com- munication language or set of protocols for communications over a network (developed specifically for the Internet). TCP/IP defines a suite or group of protocols and not only TCP and IP.

Throughput - The amount of data moved successfully from one place to another in a given time period.

UTP - Unshielded twisted pair is the most common kind of copper telephone wiring. Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electro- magnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each signal on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable.
