video, widely used within the Internet. ATM data rates range
from 45 Mbps to 2.5 Gbps. See also data rate.
authenticate To verify a user’s identity, such as by prompting for a password.
authentication server A server typically located within an ISP’s network that stores the
usernames, passwords, certificates, and other data needed to
verify users logging on to a network. See also accounting server.
binary The "base two" system of numbers, that uses only two digits, 0
and 1, to represent all numbers. In binary, the number 1 is
written as 1, 2 as 10, 3 as 11, 4 as 100, etc. Although expressed
as decimal numbers for convenience, IP addresses in actual use
are binary numbers; e.g., the IP address 209.191.4.240 is
11010001.10111111.00000100.11110000 in binary. See also bit,
IP address, network mask.
bit Short for "binary digit," a bit is a number that can have two
values, 0 or 1. See also binary.
bridging Passing data from your network to your ISP and vice versa using
the hardware addresses of the devices at each location. Bridging
contrasts with routing, which can add more intelligence to data
transfers by using network addresses instead. The Ethernet
Modem Router can perform both routing and bridging. Typically,
when both functions are enabled, the device routes IP data and
bridges all other types of data. See also routing.
broadband A telecommunications technology that can send different types
of data over the same medium. DSL is a broadband technology.
broadcast To send data to all computers on a network.
DHCP Dynamic Host Configuration Protocol
DHCP automates address assignment and management. When
a computer connects to the LAN, DHCP assigns it an IP address
from a shared pool of IP addresses; after a specified time limit,
DHCP returns the address to the pool.
DHCP relay Dynamic Host Configuration Protocol relay
A DHCP relay is a computer that forwards DHCP data between
computers that request IP addresses and the DHCP server that
assigns the addresses. Each of the Ethernet Modem Router's
interfaces can be configured as a DHCP relay. See DHCP.
DHCP server Dynamic Host Configuration Protocol server
A DHCP server is a computer that is responsible for assigning IP
addresses to the computers on a LAN. See DHCP.
DNS Domain Name System
The DNS maps domain names into IP addresses. DNS
information is distributed hierarchically throughout the Internet
among computers called DNS servers. When you start to access
a web site, a DNS server looks up the requested domain name
to find its corresponding IP address. If the DNS server cannot
find the IP address, it communicates with higher-level DNS
servers to determine the IP address. See also domain name.
domain name A domain name is a user-friendly name used in place of its
associated IP address. For example, www.globespan.net is the
domain name associated with IP address 209.191.4.240.
Domain names must be unique; their assignment is controlled by
