Chapter 5. Glossary
10Base-TA 10 Mbps Ethernet LAN that runs over twisted-pair wiring. This network interface was originally
designed to run over ordinary twisted-pair (phone wiring) but is predominantly used with Category
3 or Category 5 cabling.
VDSL Very High Data Rate Digital Subscriber Line
VDSL can service both voice and high speed data simultaneously.
A technology that delivers 13 to 52 Mbps downstream and 1.5 to 2.3 Mbps upstream over a single
copper twisted-pair. The operating range of VDSL is limited to 1,000 to 4,500 feet (304.8 to 1,372
meters) from the CO.
Ethernet A type of network that supports high-speed communication among systems. It is a widely
implemented standard for LANs developed by Xerox, Intel and DEC. All hosts are connected to
a coaxial cable where they contend for network access using a Carrier Sense, Multiple Access
with Collision Detection (CSMA/CD) paradigm.
IP Address Any computing device that uses the Internet must be assigned an Internet or IP address. This 32-
bit number is written in 4 decimal fields or "octets" separated by periods, e.g., 192.9.200.1. All
workstations on a given IP network use the same IP network number, and each workstation has a
unique IP host address and an optional subnetwork number. The network and subnetwork
numbers together are used for routing, while the host number is used to address an individual
host within the network or subnetwork. A subnet mask may be used to extract network and
subnetwork information from the IP address.
Switch Switch is a device that filers and transmits frame according to the destination address of
each frame. Switch operates in the data link layer of the OSI layer model.
TCP/IP
(Transmission
Control
Protocol/Internet
Protocol)
Transmission Control Protocol/Internet Protocol. The dominant protocol suite in the worldwide
Internet, TCP allows a process on one machine to send data to a process on another machine
using the IP. TCP can be used as a full-duplex or one-way simplex connection.
PSTN Public Switched Telephone Network. A network shared among many users who can use
telephones to establish connections between two points. Also known as dial network.
POTS
(Plain Old Telephone
Service)
Plain Old Telephone Service.
Standard telephone service over the PSTN, with an analog bandwidth of less than 4 KHz. This
term commonly refers to standard telephony, as in placing and receiving telephone calls. This is
more or less interchangeable with PSTN (Public Switched Telephone Network). A POTS splitter
enables both DSL digital data and standard telephone analog transmissions to share a single
connection.
The only name recognized around the world for basic analog telephone service. POTS takes the
lowest 4kHz of bandwidth on twisted pair wiring. Any service sharing a line with POTS must either
use frequencies above POTS or convert POTS to digital and interleave with other data signals.

WW
(World Wide Web) An Internet facility that links documents locally and remotely. The Web document, or
Web page, contains text, graphics, animations and videos as well as hypertext links.
The links in the page let users jump from page to page (hypertext) whether the pages
are stored on the same server or on servers around the world. Web pages are accessed
and read via a Web browser, the two most popular being Internet Explorer and
Netscape Navigator.. In the last half of the 1990s, the Web became "the" center of
Internet activity, because the Web browser provided an easy, point and click interface to
the largest collection of online information in the world. Ever since the Web became the
focal point of the Internet, the amount of information has increased at a staggering rate.
The Web has also turned into an online shopping mall as almost every organization has
added e-commerce capabilities. In addition, the Web has become a multimedia delivery
system as new browser features and plug-in extensions allow for audio, video,
telephony, 3-D animations and videoconferencing. Most browsers also support the Java
language, which allows applications to be downloaded from the Net and run locally.
The www. prefix used on most Web addresses is actually the mnemonic name of the
Web server used at the Web site. Most Webmasters name their servers WWW in order
to provide a recognizable address for everyone. Web addresses (URLs) are read from
right to left, so that the WWW is the last component of the address, which is the name
of the Web server itself.
