Switch - 1. Device that is the central point of connection for computers and other
devices in a network, so data can be shared at full transmission speeds. 2. A device
for making, breaking, or changing the connections in an electrical circuit.
TCP (Transmission Control Protocol) - A method (protocol) used along with
the Internet Protocol (Internet Protocol) to send data in the form of message units
between computers over the Internet. While IP takes care of handling the actual
delivery of the data, TCP takes care of keeping track of the individual units of data
(called packets) that a message is divided into for efficient routing through the In-
ternet.
TCP/IP - Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic
communication language or protocol of the Internet. It can also be used as a com-
munications protocol in a private network (either an intranet or an extranet). When
you are set up with direct access to the Internet, your computer is provided with a
copy of the TCP/IP program just as every other computer that you may send mes-
sages to or get information from also has a copy of TCP/IP.
Telnet - A user command and TCP/IP protocol used for accessing remote PCs.
TFTP (Trivial File Transfer Protocol) - A version of the TCP/IP FTP protocol
that has no directory or password capability.
Throughput - The amount of data moved successfully from one place to another
in a given time period.
Topology - A network’s topology is a logical characterization of how the devices
on the network are connected and the distances between them. The most com-
mon network devices include hubs, switches, routers, and gateways. Most large
networks contain several levels of interconnection, the most important of which
include edge connections, backbone connections, and wide-area connections.
TX Rate – Transmission Rate.
UDP (User Datagram Protocol) - A communications method (protocol)
that offers a limited amount of service when messages are exchanged between
computers in a network that uses the Internet Protocol (IP). UDP is an alternative
to the Transmission Control Protocol (TCP) and, together with IP, is sometimes re-
ferred to as UDP/IP. Like the Transmission Control Protocol, UDP uses the Internet
Protocol to actually get a data unit (called a datagram) from one computer to another.
Unlike TCP, however, UDP does not provide the service of dividing a message into
packets (datagrams) and reassembling it at the other end. Specifically, UDP doesn’t
