from DHCP server automatically. Using DHCP can save the effort of setting IP for

every LAN computers.

Dial-in

connection. Just like you dial up to ISP, Gateway Hub can act as a small ISP that

telecommuter and travelling employee can access LAN using standard dial up

program.

Dial-up Access

Refers to connecting a device to a network via a modem and a public telephone

network. Dial-up access is really just like a phone connection, except that the parties at

the two ends are computer devices rather than people. Because dial-up access uses

normal telephone lines, the quality of the connection is not always good and data rates

are limited, but new technologies such as ISDN are providing faster rates.

An alternative way to connect two computers is through a leased line, which is a

permanent connection between two devices. Leased lines provide faster throughput

and better quality connections, but they are also more expensive.

URLs to identify particular Web pages. For example, in the URL

http://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.
