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.
