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 device'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 Names and
Numbers (ICANN). Domain names are a key
element of URLs, which identify a specific file at a
web site. See DNS.
DSL Digital Subscriber Line
A technology that allows both digital data and
analog voice signals to travel over existing copper
telephone lines.
Ethernet 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.
FTP 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.
Gbps Abbreviation of Gigabits per second, or one billion
bits per second. Internet data rates are often
expressed in Gbps.
