Glossary
Networking terms and abbreviations
Host
(1) A computer (usually containing data) that is accessed by a user
working on a remote terminal, connected by modems and telephone
lines.
(2) A computer that is connected to a TCP/IP network, including the
Internet. Each host has a unique IP address.
HTTP
Hypertext Transfer Protocol is the set of rules for transferring files (text,
graphic images, sound, video, and other multimedia files) on the World
Wide Web. A Web browser makes use of HTTP. HTTP is an application
protocol that runs on top of the TCP/IP suite of protocols. (RFC2616:
Hypertext Transfer Protocol -- HTTP/1.1)
HTTPS
Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over
SSL, is a Web protocol that encrypts and decrypts user page requests
as well as the pages that are returned by the Web server. HTTPS uses
Secure Socket Layer (SSL) as a sublayer under its regular HTTP
application layering. (HTTPS uses port 443 instead of HTTP port 80 in
its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size
for the RC4 stream encryption algorithm, which is considered an
adequate degree of encryption for commercial exchange.
IBSS
Independent Basic Service Set.
See
BSS. An IBSS is the 802.11 term
for an adhoc network.
See
adhoc network.
ICMP
Internet Control Message Protocol, an extension to the Internet
Protocol (IP) defined by RFC792. ICMP supports packets containing
error, control, and informational messages. The PING command, for
example, uses ICMP to test an Internet connection.
ICV
ICV (Integrity Check Value) is a 4-byte code appended in standard
WEP to the 802.11 message. Enhanced WPA inserts an 8-byte MIC
just before the ICV. (
See
WPA and MIC)
IE
Internet Explorer.
IEEE
Institute of Electrical and Electronics Engineers, a technical
professional association, involved in standards activities.
IETF
Internet Engineering Task Force, the main standards organization for
the Internet.
Infrastructure Mode
An 802.11 networking framework in which devices communicate with
each other by first going through an Access Point (AP). In
infrastructure mode, wireless devices can communicate with each
other or can communicate with a wired network. (
See
ad-hoc mode
and BSS.)
