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.
ƒ

A DHCP server at the system headend assigns a public IP

address to the WR850.

ƒ

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
