Bridge
A hardware device that links two or more physical networks and manages the
transfer of data between these networks. The two networks connected can be
alike or dissimilar.
Broadband

different frequencies, at one time. Broadband signals use analog carriers.

Decibels Per Milliwatt (dBm)
A unit of measurement used to express relative difference in power or intensity,
relative to 1mW.
Dynamic Host Configuration Protocol (DHCP)
A method of assigning a temporary IP address to a host, such as a computer,
connected on a specific network. With dynamic addressing, a particular host may
have a different IP address each time it connects to the network.
Digital
Data expressed as a string of 0s and 1s. Each of these digits is referred to as a
bit (and a string of 8 bits that a computer can address individually as a group is a
byte).
DNS Server
A server that contains both the English and numerical addresses of all computers
connected to the Internet. When you specify an e-mail or IP address using the
"English" domain name, the DNS server will return the corresponding numeric
address.
Domain Name
A domain name locates an organization or other entity on the Internet.
Domain Name System (DNS)
This allows you to specify a symbolic name, a meaningful and easy-to-remember
"handle," instead of an Internet Protocol address. The DNS is the way that
Internet domain names are located and translated into Internet Protocol
addresses.
