H

Host - In packet- and message-switching communications networks, the collection of hardware and software that makes use of packet or message switching to support user-to-user, i.e., end-to-end, communications, interprocess communications, and distributed data processing. More simply, a server or computer on a LAN or on the Internet. The computer is reachable via the TCP/IP protocol suite from other computers.

I

Internet protocol (IP) - The method or protocol by which data is sent from one computer to another on the Internet. Each computer (known as a host) on the Internet has at least one IP address that uniquely identifies it from all other computers on the Internet. The protocol within TCP/IP that governs the breakup of data messages into packets, routing the packets from sender to destination network and station, and reassembling the packets into the original data messages at the destination.

Internet service provider (ISP) - A business that supplies Internet connectivity services to individuals, businesses, and organizations. Some ISPs are large national or multinational corporations that offer access in many locations, while others are limited to a single city or region.IP address - a 32-bit number that identifies each sender or receiver of information that is sent in packets 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. On the Internet itself - that is, between the router that move packets from one point to another along the route - only the network part of the address is looked at.

L

Local area network (LAN) - a group of computers and associated devices that share a common communications line and typically share the resources of a single processor or server.
