V.42
An ITU-T standard for modem communications that defines a two-stage
process of detection and negotiation for LAPM error control.
V.42 bis
An extension of ITU-T V.42 that defines a specific data compression
scheme for use during V.42 connections.
V.90
The ITU-T standard for 56 Kbps modem communications. This technology
uses the digital telephone network to increase the bit rate of the receive
channel by eliminating the analog to digital conversion commonly found
in modem connections. V.90 connections require a modem with V.90 or
x2 technology calling a digitally connected Internet Service Provider or
corporate host site compatible with V.90 or x2 technology.
V.92
The ITU-T standard for advanced 56 kbps modem communications. This
technology offers three new features to enhance the V.90 standard. The
first feature is V.PCM-Upstream, which allows a modem’s upstream
communication to reach speeds of 48,000 bps. The second feature
provides quicker connection times by allowing the modem to remember
the line conditions of a V.92 supported service provider. The third feature
is the Modem On Hold technology, which allows your internet
connection to be suspended when there is an inbound telephone call,
then return to the connection when the call is completed without losing
the connection. The V.92 technology can only be utilized if a V.92 modem
is dialing into an Internet Service Provider that supports and provides a
digital V.92 signal.
World Wide Web
A part of the Internet designed to allow easier navigation of the network
through the use of graphical user interfaces and hypertext links between
different addresses
