TCP (Transmission Control Protocol) - A method (protocol) used along with
the IP (Internet Protocol) to send data in the form of message units (datagram)
between network devices over a LAN or WAN. While IP takes care of handling
the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for effi-
cient delivery over the network. TCP is known as a "connection oriented" pro-
tocol due to requiring the receiver of a packet to return an acknowledgment of
receipt to the sender of the packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol) - The basic com-
munication language or set of protocols for communications over a network
(developed specifically for the Internet). TCP/IP defines a suite or group of pro-
tocols and not only TCP and IP.
Throughput - The amount of data moved successfully from one place to anoth-
er in a given time period.
Upgrade - To replace existing software or firmware with a newer version.
Upload - To transmit a file over a network. In a communications session, upload
means transmit, download means receive.
URL (Uniform Resource Locator) - The address that defines the route to a file
on the Web or any other Internet facility. URLs are typed into the browser to
access Web pages, and URLs are embedded within the pages themselves to pro-
vide the hypertext links to other pages.
UTP - Unshielded twisted pair is the most common kind of copper telephone
wiring. Twisted pair is the ordinary copper wire that connects home and many
business computers to the telephone company. To reduce crosstalk or electro-
magnetic induction between pairs of wires, two insulated copper wires are twist-
ed around each other. Each signal on twisted pair requires both wires. Since
some telephone sets or desktop locations require multiple connections, twisted
pair is sometimes installed in two or more pairs, all within a single cable.
WAN (Wide Area Network)- A communications network that covers a relative-
ly large geographic area, consisting of two or more LANs. Broadband commu-
nication over the WAN is often through public networks such as the telephone
(DSL) or cable systems, or through leased lines or satellites. In its most basic
definition, the Internet could be considered a WAN.
Workgroup - Two or more individuals that share files and databases.
