IETF Internet Engineering Task Force. One of the task forces of the IAB
(Internet Architecture Board), formally called the Internet Activities
Board, which is the technical body that oversees the development of
the Internet suite of protocols (commonly referred to as
"TCP/IP").The IETF is responsible for solving short-term engineering
needs of the Internet.
IF
Intermediate Frequency. Radio communications systems modulate a
carrier frequency with a baseband signal in order to achieve radio
transmission. In many cases, the carrier is not modulated directly.
Instead, a lower IF signal is modulated and processed. At a later
circuit stage, the IF signal is converted up to the transmission
frequency band.
IP
Internet Protocol. The standard that defines how data is transmitted
over the Internet. IP bundles data, including e-mail, faxes, voice
calls and messages, and other types, into "packets", in order to
transmit it over public and private networks.
IPsec
Security Architecture for IP Network. IP Control Protocol (IPCP) and
IPv6 Control Protocol IPsec provides security services at the IP layer
by enabling a system to select required security protocols, determine
the algorithm(s) to use for the service(s), and put in place any
cryptographic keys required to provide the requested services. IPsec
can be used to protect one or more "paths" between a pair of hosts,
between a pair of security gateways, or between a security gateway
and a host.
ISP
Internet Service Provider
ITU-T International Telecommunication Union - Telecommunications. An
intergovernmental organization through which public and private
organizations develop telecommunications. The ITU was founded in
1865 and became a United Nations agency in 1947. It is responsible
for adopting international treaties, regulations and standards
governing telecommunications. The standardization functions were
formerly performed by a group within the ITU called CCITT, but after
a 1992 reorganization the CCITT no longer exists as a separate
entity.
LAN Local area Network. A computer network limited to a small
geographical area, such as a single building. The network typically
links PCs as well as shared resources such as printers.
LED
Light Emitting Diode.
