IP Address An IP address is a 32-bit number that identifies each sender or receiver of information sent

across the Internet. An IP address has two parts: the identifier of a particular network on the
Internet and an identifier of the particular device (which can be a server or a workstation) within
that network.

ISP Internet Service Provider. An organization that provides access to the Internet. Small ISPs

provide service via modem and ISDN while the larger ones also offer private line hookups (T1,
fractional T1, etc.).

LAN Local Area Network. A communications network that serves users within a defined

geographical area. The benefits include the sharing of Internet access, files, and equipment, such
as printers and storage devices. Special network cabling (10BaseT) is often used to connect the
PCs together.

NAT Network Address Translation. The translation of an Internet Protocol address (IP address) used

within one network to a different IP address known within another network. One network is
designated the internal network and the other is the external. The internal network then appears
as one entity to the outside world.
