Bluetooth Protocol (Part 2): Types, Data Exchange, Security
Bluetooth is defined as layered protocol architecture because each layer supports the layer above and below it. The complete protocol stack consists[[wysiwyg_imageupload::]] of both Bluetooth specific protocols which are clearly defined or developed for Bluetooth like LMP and non-Bluetooth specific that were designed to enable the re-use of existing protocols for various functions.

Video Conferencing
“A small step for man, but a giant leap for mankind”, such were the words that travelled through space all the way from the Moon to our television sets as frames of Armstrong’s setting foot on the moon flashed across 600 million screens. It was indeed a technological milestone. But have ever wondered that people were sitting in their living rooms watching a mortal reach an alien land and show to you live pictures from there. Much before that feat, the technology to transmit video had been developed and was in itself a technological achievement. About half a century later, two-way communication involving real-time streaming of video and audio is becoming commonplace with almost every smart phone. Videoconferencing is a technology by means of which two or more parties situated in different geographical locations can watch and converse with each other by means of two-way transmission of video and audio data in near real-time. From once being a high profile, owned by a famous few, this technology has made inroads to every middle class homestead that owns a healthy broadband connection.
