Which of the following is a technology that allows you to hear and watch video clips as soon as they
start downloading from the Web site, instead of waiting for the download to complete?

A.
Session Initiation Protocol

B.
HTTP streaming

C.
Streaming media

D.
Slipstreaming

Explanation:

Streaming media is a technology that allows you to hear and watch video clips as soon as they start
downloading from the Web site, instead
of waiting for the download to complete.
Answer B is incorrect. HTTP streaming is a simple mechanism for sending data from a Web server to
a Web browser in response to an
event. Every time a seek operation is performed, the media player makes a request to the server
side script with a couple of GET variables.
One is the file to play and one is the start position. The server side script then starts the video from
the offset given. For example, after
starting the video, a user can jump directly to any part in the video without having to wait until it is
loaded.
Answer A is incorrect. Session Initiation Protocol (SIP), designed by Henning Schulzrinne and Mark
Handley in 1996, is a signaling

protocol, widely used for setting up and tearing down multimedia communication sessions such as
voice and video calls over the Internet
(VoIP).
Answer D is incorrect. Slipstreaming is a process of integrating service pack updates into the
Windows XP Professional setup files. The
slipstreaming process eliminates the need of deploying service pack update on each computer
separately.
