Motorola SVG2500 manual Term Definition DNS, Docsis, Dsl, Dsss

17 GLOSSARY
TERM	DEFINITION
DNS	The Domain Name System is the Internet system for converting
	domain names 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 names to IP address matches.
DOCSIS	The CableLabs Data-Over-Cable Service Interface Specification
	defines interface standards for cable modems, gateways, and
	supporting equipment to deliver data between an HFC network
	and computer systems or television sets. To emphasize its use
	as a cable modem standard, DOCSIS is now called CableLabs
	Certified Cable Modems. Euro-DOCSIS is DOCSIS adapted for
	use in Europe.
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.
dotted-decimal	A method of representing an IP address or subnet mask using
format	four decimal numbers called octets. Each octet represents
	eight bits.
	In a class C IP address, the octets are
	“network.network.network.host.” The first three octets
	together represent the network address and the final octet is
	the host address. In the SVG2500 LAN default configuration,
	192.168.100 represents the network address. In the final octet,
	the host address can range from 2 to 254.
download	To copy a file from one computer to another. You can use
	the Internet to download files from a server to a computer.
	A DOCSIS or Euro-DOCSIS cable modem or gateway
	downloads its configuration file from a TFTP server during start-
	up.
downstream	In a cable data network, the direction of data received by the
	computer from the Internet.
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
DSSS	Direct Sequence Spread Spectrum is an IEEE 802.11b RF
	modulation protocol.
