Glossary of Terms

Store and Forward:

Technique for examining incoming packets on an Ethernet switch or bridge whereby the whole packet is read before forwarding or filtering takes place. Store and forward is a slightly slower process than cut-through, but it does ensure that all bad or misaligned packets are eliminated from the network by the switching device.

SPX:

Sequential Packet exchange. Novell's implementation of SPP (Sequential Packet Protocol).

SQE:

Ethernet-defined signal quality test function, frequently called "heartbeat."

Switch:

Multiport Ethernet device designed to increase network performance by allowing only essential traffic on the attached individual Ethernet segments. Packets are filtered or forwarded based upon their source and destination addresses.

T-Connector:

A T-shaped device with two female and one male BNC connectors.

TCP/IP:

Transmission Control Protocol (TCP) and Internet Protocol (IP) are the standard network protocols in UNIX environments. They are almost always implemented and used together and called TCP/IP.

Telnet:

Telnet is an application that provides a terminal interface between hosts using the TCP/IP network protocol. It has been standardized so that "telnetting" to any host should give one an interactive terminal session, regardless of the remote host type or operating system. Note that this is very different from the LAT software, which allows only local network access to LAT hosts only.

10BASE2:

Ethernet running on thin coax network cable.

10BASE5:

Ethernet running on Thickwire network cable.

10BASE-T:

Ethernet running on unshielded twisted pair (UTP) cable. Note that 10BASE-T is a point-to-point network media, with one end of the cable typically going to a repeater/hub and the other to the network device.
