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.
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
ADSL Router RTA01N's interfaces can be configured as a
DHCP relay. See DHCP.
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.
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.
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.
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 Names and Numbers (ICANN). Domain names are
a key element of URLs, which identify a specific file at a web
site. See DNS.
To transfer data in the downstream direction, i.e., from the
Internet to the user.
Digital Subscriber Line
A technology that allows both digital data and analog voice
signals to travel over existing copper telephone lines.
See network keys
The most commonly installed computer network technology,
usually using twisted pair wiring. Ethernet data rates are 10
Mbps and 100 Mbps. See also 10BASE-T, 100BASE-T,
twisted pair.
File Transfer Protocol
A program used to transfer files between computers
connected to the Internet. Common uses include uploading
new or updated files to a web server, and downloading files
from a web server.
Abbreviation of Gigabits per second, or one billion bits per
second. Internet data rates are often expressed in Gbps.
A device (usually a computer) connected to a network.
