domain
domain. In the Internet, a part of the naming hierarchy. Syntactically, a domain name
consists of a sequence of names (labels) separated by periods (dots).
Ethernet. A popular local area network (LAN) technology invented at the Xerox Corporation
Palo Alto Research Center. An Ethernet itself is a passive coaxial cable; the
interconnections all contain active components. Ethernet is a best-effort delivery
system that uses CSMA/CD technology. Xerox Corporation, Digital Equipment
Corporation, and Intel Corporation developed and published the standard for 10 Mbps
Ethernet.
File Transfer Protocol (FTP). The Internet standard, high-level protocol for transferring files
from one machine to another. Usually implemented as application-level programs, FTP
uses the TELNET and Transmission Control Protocol (TCP) protocols. The server side
requires a web client to supply a login identifier and password before it will honor
requests .
FTP. See File Transfer Protocol (FTP).
gateway. A special-purpose, dedicated computer that attaches to two or more networks and
routes packets from one to the other. In particular, an Internet gateway routes Internet
Protocol (IP) datagrams among the networks to which it is connected. Gateways route
packets to other gateways until they can be delivered to the final destination directly
across one physical network. The term is loosely applied to any machine that transfers
information from one network to another, as in mail gateway.
hierarchical routing. Routing based on a hierarchical addressing scheme. Most Internet
routing is based on a two-level hierarchy in which an Internet address is divided into a
network portion and a host portion. Gateways use only the network portion until the
datagram reaches a gateway that can deliver it directly. Subnetting introduces
additional levels of hierarchical routing
HyperText Markup Language (HTML). The tagging language used to format HyperText
documents on the World Wide Web. It is built on top of Standard Generalized Markup
Language (SGML).
HyperText Transport Protocol (HTTP). The communications protocol used for transmitting
data between servers and web clients (browsers) on the World Wide Web.
IEEE. See Institute of Electrical and Electronics Engineers (IEEE).
Institute of Electrical and Electronics Engineers (IEEE). An international industry group
that develops standards for many areas of electrical engineering and computers.
Internet address. The 32-bit address assigned to hosts that want to participate in the
Internet using TCP/IP. Internet addresses are the abstraction of physical hardware
addresses, just as the Internet is an abstraction of physical networks. Actually
assigned to the interconnection of a host to a physical network, an Internet address
consists of a network portion and a host portion. The partition makes routing efficient.
