DHCP
A Dynamic Host Configuration Protocol server dynamically
assigns IP addresses to client hosts on an IP network. DHCP
eliminates the need to manually assign static IP addresses by
“leasing” an IP address and subnet mask to each client. It
enables the automatic reuse of unused IP addresses:
The WR850 is simultaneously a DHCP client and a DHCP server.
A DHCP server at the system headend assigns a public IP
address to the WR850.
The WR850 contains a built-in DHCP server that assigns
private IP addresses to clients.
DMZ
DeMilitarized Zone. This service opens one IP address to the
Internet, usually for online gaming, and acts as a buffer between
the Internet and your network.
DNS
The Domain Name System is the Internet system for converting
domain names (like
www.motorola.com ) to IP addresses. A DNS
server contains a table matching domain names such as
Internetname.com to IP addresses such as 192.169.9.1. When
you access the world-wide web, a DNS server translates the URL
displayed on the browser to the destination website IP address.
The DNS lookup table is a distributed Internet database; no one
DNS server lists all domain name to IP address matches.
Domain Name
A unique name, such as motorola.com, that maps to an IP
address. Domain names are typically much easier to remember
than are IP addresses. See DNS.
Download
To copy a file from one computer to another. You can use the
Internet to download files from a server to a computer.
Driver
Software that enables a computer to interact with a network or
other device. For example, there are drivers for printers, monitors,
graphics adapters, modems, Ethernet, USB, HPNA, and many
others.
DSL
Digital Subscriber Line
