Explanation
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.
Independent Basic Service Set. See BSS. An IBSS is the 802.11 term for an
adhoc network. See adhoc network.
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 (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)
Internet Explorer.
Institute of Electrical and Electronics Engineers, a technical professional
association, involved in standards activities.
Internet Engineering Task Force, the main standards organization for the
Internet.
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.)
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.
Internet Protocol is the method or protocol by which data is sent from one
computer to another on the Internet. Each computer (host) on the Internet
has at least one IP address that uniquely identifies it. Internet Protocol
specifies the format of packets, also called datagrams, and the addressing
scheme. Most networks combine IP with a higher-level protocol called
Transmission Control Protocol (TCP), which establishes a virtual
connection between a destination and a source.
