Forwarding Rate
The maximum rate at which 64K packets can be delivered to their destination. See also,
Packet, Packet Switching Network, pps, and Throughput.
Fragment Length
(Fragmentation)
Breaking a packet into smaller units when transmitting over a network medium that
cannot support the original size of the packet. The fragment length value should remain
at its default setting unless you experience a high packet error rate. Setting the
fragment length too low may result in poor performance.
FTP
(File Transfer Protocol) A standard protocol used for copying and moving files quickly,
efficiently, and securely across public and private networks. An FTP site is one where
files are available for downloading and uploading. FTP sites usually require a secure
login (name and password) to gain access.
Gateway
Any device that provides a seamless connection between otherwise incompatible
systems.
Gopher
A computer program, and an accompanying data transfer protocol, for reading
information that has been made available to the public on the Internet. Gopher is
gradually being superseded by HTML.
Home Page
Usually the first page users see when they visit a Web site (if they address the home
page’s URL). A well-constructed Web site will normally consist of a home page that
provides a clear and concise overview of the entire Web site, together with the tools for
accessing other pages and topics quickly and efficiently. In this case, the home page is
the “portal” to the Web site. See also, Portal and URL.
Host
Any computer that provides services to other computers that are linked to it by a
network. Generally, the host is the more remote of the computers. For example, if a user
in California accesses a computer in New York, the computer in New York is considered
the host.
HPR
(Home Page Redirection) Nomadix Gateways enable solution providers to redirect
subscribers to a “portal” home page of their choice. This allows the solution provider to
generate online advertising revenues and increase business exposure. See also, Home
Page.
HTML
(HyperText Markup Language) The programming language used to create hypertext
documents for use on the Internet. See also, HTTP, Hypertext, and Internet.
HTTP
(HyperText Transfer Protocol) The standard method used for publishing hypertext
documents in HTML format on the Internet. See also, HTML and Internet.
Hypertext
Electronic documents that are structured to enable readers to go directly to the source
of the information they need by following directional links (unlike books which are
generally read sequentially). Web pages and help file are examples of hypertext
documents.
ICMP
(Internet Control Message Protocol) A standard Internet protocol that delivers error and
control messages from hosts to message requesters. An ICMP echo test can determine
whether a target destination is reachable. An ICMP echo test is also called a ping. See
also, Ping.
IEEE
(Institute of Electrical and Electronics Engineers) Founded in 1884, the IEEE is an
organization composed of engineers, scientists, and students. The IEEE is best known
for developing standards for the computer and electronics industry. In particular, the
IEEE 802 standards for Local Area Networks are widely followed.
