ISP
Short for Internet Service Provider, a company that provides
access to the Internet. For a monthly fee, the service provider gives
you a software package, username, password and access phone
number. Equipped with a modem, you can then log on to the Internet
and browse the World Wide Web and USENET, and send and receive
e-mail.
Local Area Network (LAN)
A computer network that spans a relatively small area. Most
LANs are confined to a single building or group of buildings. However,
one LAN can be connected to other LANs over any distance via
telephone lines and radio waves. A system of LANs connected in this
way is called a wide-area network (WAN)
MAC Address
Short for Media Access Control address, a hardware address
that uniquely identifies each node of a network. In IEEE 802 networks,
the Data Link Control (DLC) layer of the OSI Reference Model is
divided into two sublayers: the Logical Link Control (LLC) layer and the
Media Access Control (MAC) layer. The MAC layer communicate
directly with the network media. Consequently, each different type of
network media requires a different MAC layer.
TCP/IP
Acronym for Transmission Control Protocol/Internet Protocol,
the suite of communications protocols used to connect hosts on the
Internet.
