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.
