GESA
GESA. See Gigabit Ethernet ServerNet Adapter (GESA).
Gigabit Ethernet ServerNet Adapter (GESA). A A single-port ServerNet adapter that
provides 1000 megabits/second (Mbps) data transfer rates between HP NonStop™
systems and Ethernet LANs. A GESA can be directly installed in slots 51 through 54 of
an I/O enclosure and slots 53 and 54 of a processor enclosure.
Two versions of the GESA are available:

3865 GESA-C (T523572): a single-port copper version compliant with the 1000
Base-T standard (802.3ab)

3865 GESA-F (T523572): a single-port fiber version compliant with the 1000 Base-
SX standard (802.z)
Handler. Exports LogRecord objects to a variety of destinations including memory, output
streams, consoles, files, and sockets. A variety of Handler subclasses exist for this
purpose. Additional Handlers may be developed by third parties and delivered on top
of the core platform.
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.
high-availability. Continuous availability of service that NSJSP offers.
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.
