GESA
across one physical network. The term is loosely applied to any machine that transfers
information from one network to another, as in mail gateway.
GESA. See Gigabit Ethernet ServerNet Adapter (GESA).
Gigabit Ethernet ServerNet Adapter (GESA). A single-port ServerNet adapter that
provides Gigabit connectivity on a NonStop S-series server. The GESA installs directly
into an existing Ethernet port, and multiple GESAs are supported in a system
enclosure.
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.
Internet Protocol (IP). The Internet standard protocol that defines the Internet datagram as
the unit of information passed across the Internet and that provides the basis for the
Internet connectionless, best-effort packet delivery service.
Internet. Physically, a collection of packet-switching networks interconnected by gateways,
along with protocols that allow them to function logically as a single, large, virtual
network. When written in uppercase, INTERNET refers specifically to the DARPA
Internet and the TCP/IP protocols it uses.
interoperability. The ability of software and hardware on multiple machines from multiple
vendors to communicate meaningfully.
IP. See Internet Protocol (IP).
J2EE. See Java 2 Platform Enterprise Edition (J2EE)
