Glossary
10 BaseT
An Ethernet local area network that works on twisted pair wiring.
100 BaseT
A newer version of Ethernet that operates at 10 times the speed of a 10 BaseT Ethernet.
Domain Name Server (DNS)
Internet service that translates domain names into IP addresses. To use a domain name, a DNS service must
translate the name into the corresponding IP address. For instance, the domain name
www.example.com
might translate to 198.105.232.4.
Dual-Tone Multi-Frequency (DTMF)
In telephone systems, multi-frequency signalling in which a standard set combinations of two specific voice
band frequencies, one from a group of four low frequencies and the other from a group of four higher
frequencies, are used. Although some military telephones have 16 keys, telephones using DTMF usually have
12 keys. Each key corresponds to a different pair of frequencies. Each pair of frequencies corresponds to one
of the ten decimal digits, or to the symbol “#” or “*”, the “*” being reserved for special purposes.
Dynamic Host Configuration Protocol (DHCP)
TCP/IP protocol that enables PCs and workstations to get temporary or permanent IP addresses (out of a pool)
from centrally-administered servers.
Federal Communications Commission (FCC)
U.S. government regulatory body for radio, television, interstate telecommunications services, and
international services originating in the United States.
Gateway
A device linking two different types of networks that use different protocols (for example, between the packet
network and the Public Switched Telephone Network).
Integrated Services Digital Network (ISDN)
A set of digital transmission protocols defined by the international standards body for telecommunications, the
ITU-T (formerly called the CCITT). These protocols are accepted as standards by virtually every
telecommunications carrier all over the world.
ISDN complements the traditional telephone system so that a single pair of telephone wires is capable of
carrying voice and data simultaneously. It is a fully digital network where all devices and applications present
themselves in a digital form.
International Telecommunication Union (ITU)
Organization based in Geneva, Switzerland, that is the most important telecom standards-setting body in the
world.
Internet Protocol (IP)
A standard describing software that keeps track of the Internet’s addresses for different nodes, routes outgoing
messages, and recognizes incoming messages.
Light Emitting Diode (LED)
A semiconductor diode that emits light when a current is passed through it.
