Bandwidth
A measure of capacity of communications media. Greater bandwidth allows
communication of more information in a given period of time. Bandwidth is
generally described either in terms of analog signals in units of Hertz (Hz),
which describes the maximum number of cycles per second, or in terms of
digital signals in units of bits per second.
Bridge
A device that connects two local-area networks (LANs), or two segments of
the same LAN that use the same protocol, such as Ethernet.
Broadcast
To simultaneously send the same message to multiple recipients.
- C -
CBR
Short for Constant Bit Rate. A type of ATM service which specifies a fixed
bit rate so that data is sent in a steady stream. This is analogous to a
leased line.
CRC
Abbreviation of Cyclic Redundancy Check, a common technique for
detecting data transmission errors.

Device
Any machine or component that attaches to a computer. Examples of
devices include disk drives, printers, mice and modems.
DHCP
Short for Dynamic Host Configuration Protocol, which is a protocol
for assigning dynamic IP addresses to devices in a network. With
dynamic addressing, a device can have a different IP address every
time it connects to the network. Many ISPs use dynamic IP
addressing for dial-up users.
DMZ
A Demilitarized Zone is used by a company that wants to host its own
Internet services without sacrificing unauthorized access to its private
network. The DMZ sits between the Internet and an internal network's line
of defense, usually some combination of firewalls and bastion hosts.
