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.)
Internet or IP telephony IP or Internet telephony are communications, such as voice, facsimile,
voice-messaging applications, that are transported over the Internet,
rather than the public switched telephone network (PSTN). IP
telephony is the two-way transmission of audio over a packet-
switched IP network (TCP/IP network).
An Internet telephone call has two steps: (1) converting the analog
voice signal to digital format, (2) translating the signal into Internet
protocol (IP) packets for transmission over the Internet. At the
receiving end, the steps are reversed. Over the public Internet, voice
quality varies considerably. Protocols that support Quality of Service
(QoS) are being implemented to improve this.
