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 Wireless Gateway 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
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 Wireless Gateway'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
.
Digital
Of data, having a form based on discrete values expressed as binary numbers (0's and 1's).
The data component in DSL is a digital signal. See
analog
.
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. For example,
www.yahoo.com
is
the domain name associated with IP address 216.115.108.243. 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
domain name.
Domain name
A domain name is a user-friendly name used in place of its associated IP address. Domain
names must be unique; their assignment is controlled by the Internet Corporation for Assigned
