Workshop

See protocol stack.
STP
See shielded twisted pair.
suite
A term used to describe a collection of similar protocols. This term is used primarily when
describing TCP- and IP-based protocols (when talking about the “TCP/IP suite”).
TCP/IP
Transmission Control Protocol/Internet Protocol. The protocols used by the Internet.
Telnet authentication option
Protocol options for Telnet that add basic security to Telnet-based connections, based on rules at
the source routing level. Refer to RFC 1409 for details.
Telnet
A protocol and an application. Telnet allows you to control your system from remote locations.
During a Telnet session, your machine responds much as it would if you were actually working on
its console.
TEMPEST
Transient Electromagnetic Pulse Surveillance Technology. TEMPEST is the practice and study of
capturing or eavesdropping on electromagnetic signals that emanate from any device (in this case,
a computer). TEMPEST shielding is any computer security system designed to defeat such
eavesdropping.
terabyte
1,099,511,627,776 bytes (abbreviated as TB).
terminator
A small plug that attaches to the end of a segment of coax Ethernet cable. This plug provides a
resistor to keep the signal within specifications.
TFTP
See Trivial File Transfer Protocol.
Token-Ring
A network that’s connected in a ring topology, in which a special “token” is passed from
computer to computer. A computer must wait until it receives this token before sending data over
the network.
topology
The method or systems by which your network is physically laid out. For example, Ethernet and
Token-Ring are both network topologies, as are “star” versus “bus” wiring. The former is a
network topology; the latter is a physical topology.
traceroute
A TCP/IP program common to UNIX that records the routers used between your machine and a
remote host. Available on Windows as tracert.
traffic analysis
The study of patterns in communication rather than the content of the communication. For
example, studying when, where, and to whom particular messages are being sent, without actually
studying the content of those messages.
