Straight A cable that wires a pin to its equivalent pin. This cable connects two dissimilar
Through devices, for example, a data terminal equipment (DTE) device and a data
Ethernet Cable communications equipment (DCE) device. A straight through Ethernet cable is
the most common cable used.
Switched 56 Digital service at 56 Kbps provided by local telephone companies and long
distance carriers. Similar to ISDN, Switched 56 traffic can travel over the same
physical infrastructure that supports ISDN. Switched 56, however, is an older
technology with decreasing significance.
Symbol Speed Speed at which a signaling unit is transferred. In modern modem modulation, a
signaling unit is no longer a single bit. Thus, the bit speed is different from the
symbol speed.
Synchronous In synchronous transfer, a dedicated control signal line transmits a clock signal
that paces the transmitted data. In high-speed connections, the transfer
between two modems is always synchronous, even if the DCE to DTE
connection is asynchronous.
T.30 A standard for fax transfers.
TAE6 A standard for a telephone wall outlet used in some countries, particularly in
Germany.
Telnet is the login and terminal emulation protocol common on the Internet and
Telnet
in UNIX environments. It operates over TCP/IP networks. Its primary function is
to allow users to log into remote host systems.
Tempest Illegal interception of data from computers and video signals.
ter Old French word for three.
Terminal A device that allows you to send commands to a computer somewhere else. At
a minimum, this usually means a keyboard and a display screen and some
simple circuitry.
Terminal A computer running terminal software is used as terminal equipment in modem
Equipment connections.
Terminal Software that pretends to be (emulates) a physical terminal and allows you to
Software type commands to a computer somewhere else.
Token A token is a re-encoding of information in less bits; basically an abbreviation.
