Gateway
A gateway is a network node that serves as an entrance to another network. A gateway
also often provides a proxy server and a firewall. It is associated with both a router, which
use headers and forwarding tables to determine where packets are sent, and a switch or
bridge, which provides the actual path for the packet in and out of the gateway.
Before a host on a
LAN can access the Internet, it needs to know the address of its default
gateway.
HTML
The Hypertext Markup Language (
HTML) defines the structure of a document on the World
Wide Web. It uses tags and attributes to hint about a layout for the document.
An HTML document starts with an <html> tag and ends with a </html> tag. A correctly
formatted document also contains a <head> ... </head> section, which contains the
metadata to define the document, and a <body> ... </body> section, which contains its
content. Its markup is derived from the Standard Generalized Markup Language (SGML),
which is defined in ISO 8879:1986.
HTML documents are sent from server to browser through
HTTP. Also see XML.
HTTP
The Hypertext Transfer Protocol (HTTP) defines how messages are formatted and transmitted
on the World Wide Web. An HTTP message consists of a URL and a command (GET, HEAD,
POST, and so on), a request followed by a response.
IAPP
The Inter Access Point Protocol (IAPP) is an
IEEE standard (802.11f) that defines
communication between the access points in a “distribution system”. This includes the
exchange of information about mobile stations and the maintenance of bridge forwarding
tables, plus securing the communications between access points.
IBSS
An independent basic service set (IBSS) is an
Ad-hoc Mode Wireless Networking Framework
in which stations communicate directly with each other.
IEEE
The Institute of Electrical and Electronic Engineers (IEEE) is an international standards
body that develops and establishes industry standards for a broad range of technologies,
including the 802 family of networking and wireless standards. (See
802, 802.1x, 802.11,
802.11a, 802.11b, 802.11e, 802.11f, 802.11g, and 802.11i.)
