Appendix B GlossaryDHCPDHCP is a protocol for automatic IP configuration. Client side computer can get one IPfrom DHCP server automatically. Using DHCP can save the effort of setting IP forevery LAN computers.Dial-inDial in is the function for remote user to access office LAN by Modem/ISDN TAconnection. Just like you dial up to ISP, Gateway Hub can act as a small ISP thattelecommuter and travelling employee can access LAN using standard dial upprogram.Dial-up AccessRefers to connecting a device to a network via a modem and a public telephonenetwork. Dial-up access is really just like a phone connection, except that the parties atthe two ends are computer devices rather than people. Because dial-up access usesnormal telephone lines, the quality of the connection is not always good and data ratesare 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 apermanent connection between two devices. Leased lines provide faster throughputand better quality connections, but they are also more expensive.Domain NameA name that identifies one or more IP addresses. For example, the domain namemicrosoft.com represents about a doze IP addresses. Domain names are used inURLs to identify particular Web pages. For example, in the URLhttp://www.pcwebopedia.com/index.html, the domain name is pcwebopedia.com.IEEEAbbreviation of Institute of Electrical and Electronics Engineers, pronounced I-triple-E.Founded in 1884, the IEEE is an organization composed of engineers, scientists, andstudents.
