File Transfer Protocol (FTP)
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.
GESA. See Gigabit Ethernet ServerNet Adapter (GESA).
Gigabit Ethernet ServerNet Adapter (GESA). A single-port ServerNet adapter that 
provides Gigabit connectivity on NonStop servers. 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.
Instrumentation. The procedure of collecting statistics from the desired WebServer on 
certain configured parameters
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.
