Glossary

I

IP (Internet Protocol)

The Internet Protocol is the network layer for the TCP/IP Protocol Suite. It is a connectionless, best-effort packet switching protocol.

Intranet

An Intranet is the use of Internet technologies within a company. Intranets are private networks that exist only within organizations, while the Internet is a global network open to all.

IP Addresses

A computer on the Internet is identified by an IP Address. A computer’s IP address is like a telephone number. It identifies one address or in this case one computing device. Every computer or device on the network must have a different IP address.

An IP address consists of four groups of numbers called octets, which are separated by periods. For example, 213 .0.0.1 is an IP address. An IP address consists of a network portion and a host portion. The network portion identifies the subnet that the computer belongs to. The host portion identifies the particular computer or node on that network.

IP addresses can either be dynamic (temporary) or static (permanent or fixed). A dynamic IP address is a temporary IP address that is assigned to you by a server (usually a DHCP server) when the computer is powered on. A static IP address is a permanent IP address that is set up on each individual computer. When your RouteFinder dials-up your ISP, your ISP can give it a fixed or dynamic IP address. Likewise when you power on your computer, the RF500S can give your computer a dynamic or fixed IP address.

ISDN TA

(Integrated Services Digital Network Terminal Adapter) ISDN is a high speed digital telephone connection involving the digitization of the telephone network using existing wiring. An ISDN Terminal Adapter can be thought of as an ISDN Modem.

ISP (Internet Service Provider)

An organization that provides Internet services. An ISP is the company that provides the connection from your computer to the Internet. An ISP can offer a range of services, such as dial-up accounts, e-mail, web hosting or News.

L

LAN (Local Area Network)

A data network intended to serve an area of only a few square kilometers or less. This often means a small private network in companies.

M
