Appendix C - Glossary

ADSL:	Asymmetric Digital Subscriber Line (ADSL), as its name indicates, is an
	asymmetrical data transmission technology with higher traffic rate
	downstream and lower traffic rate upstream. ADSL technology satisfies
	the bandwidth requirements of applications which demand asymmetric
	traffic, such as web surfing, file downloads, and telecommuting.
Bandwidth:	The amount of data that can be transmitted in a fixed amount of time.
DHCP:	Dynamic Host Configuration Protocol (DHCP) is a protocol for
	assigning dynamic IP Addresses to devices on a network. Dynamic
	Addressing means that a device can have a different IP Address each time
	it connects to the network.
DNS:	Domain Name Server (DNS), translates domain names into IP Addresses.
	To help us recognize and remember domain names they are alphabetic in
	form, however, the Internet actually runs on numbered IP Addresses.
	DNS servers translate domain names into their respective IP Addresses.
Ethernet:	One of the most common Local Area Network (LAN) standards.
	Ethernet uses a bus topology which supports a data transfer rate of 10
	or 100 Mbps.
DMZ:	In computer networks, a DMZ (demilitarized zone) is a computer host
	or small network inserted as a "neutral zone" between a company's
	private network and the outside public network. It prevents outside
	users from getting direct access to a server that has company data. A
	DMZ is an optional and more secure approach to a firewall and
	effectively acts as a proxy server as well.
Domain Name:	A name that identifies one or more IP Addresses. For example, the
	domain name microsoft.com represents about a dozen IP Addresses.
	Domain names are used in URLs to identify particular Web pages. For
	example, in the URL http://www.pcwebopedia.com/index.html, the
	domain name is pcwebopedia.com.
Firewall:	A security system used to enforce an access control policy between an
	organisation’s networks and the Internet.
Gateway:	A gateway is a network point that acts as an entrance to another
	network.
IPSec:	Internet Protocol Security is a security standard for network
	transmission, which is often used for VPN connections. It provides
	authentication and packet encryption over the Internet.
