symbol rate Also known as baud rate, is a measure of the number of times per second a signal in a
communications channel varies, or makes a transition between states (states being frequencies,
voltage levels or phase angles). Usually measured in symbols per second (sps).

TCP Transmission Control Protocol on
for data transmitted using
procedures for data exchange between hosts on top of connectionless IP. TCP uses a timer to track
outstanding packets, checks error in incoming packets, and retransmits packets if requested.
TCP/IP The Transmission Control Protocol/Internet Protocol suite provides standards and rules for data
communication between networks on the Internet. It is the worldwide internetworking standard and the
basic communications protocol of the Internet.
TFTP Trivial File Transfer Protocol is a very simple

transport layer Layer of the OSI concerned with protocols for error recognition and recovery. This layer also regulates
information flow.
trunk Electronic path over which date is transmitted.
TTL The time to live is the number of
a router processes an packet, it decreases the TTL by 1. When the TTL reaches zero, the packet is
discarded.
tunnel To place packets inside other packets to send over a network. The
understood by each endpoint, or tunnel interface, where the packet enters and exits the network.
VPNs rely on tunneling to create a secure network.
Tunneling requires the following protocol types:
• A carrier protocol, such as TCP, used by the network that the data travels over
• An encapsulating protocol, such as IPSec, L2F, L2TP, or PPTP, that is wrapped around the original
data
• A passenger protocol, such as IP, for the original data
two-way A cable system that can transmit signals in both directions to and from the
subscriber.
