iTP Secure WebServer System Administrators Guide (Version 7.5+)

Glossary
This glossary defines terms used both in this manual and in other HP manuals. Both
industry-standard terms and HP-specific terms are included.
browser. A graphical user interface (GUI) used to access sites on the World Wide Web. Netscape, Internet
Explorer, Mosaic, and Lynx are commonly used browsers.
CERN. The European Laboratory for particle physics. The originators of the Hypertext Transport Protocol
(HTTP) and Hypertext Markup Language (HTML) concepts.
CGI. See Common Gateway Interface (CGI)
CommerceNet. A consortium that was formed in Silicon Valley to promote electronic commerce over the Internet.
Common Gateway
Interface (CGI).
A standard protocol used as the interface between Web servers and the programs these servers
use to process requests from Web clients.
connection. The path between two protocol modules that provides reliable stream delivery service. In the
Internet, a connection extends from a Transmission Control Protocol (TCP) module on one machine
to a TCP module on another machine.
deployment
descriptor.
The web.xml file that contain resource definitions such as MIME types, mapping of requests to
servlets, access control and servlet initialization parameters.
disk files. Standard POSIX or Guardian style disk files. The file names of POSIX disk files comply with the
POSIX specifications.
distinguished
name (DN).
The complete name of a directory entry, consisting of the Relative Distinguished Name (RDN) of
the entry and the RDNs of its superior entries.
DN. See distinguished name (DN)
DNS. See Domain Name Server (DNS).
Domain Name
Server (DNS).
A method for naming resources. The basic function of the DNS is to provide information about
network objects by answering queries.
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.
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.
