MQTT Protocol

MQTT stands for Message Queuing Telemetry Transport and is a lightweight publish/subscribe messaging protocol for Machine to Machine(M2M) telemetry in low bandwidth environments. It was developed in 1999 by Arlen Nipper and Andy Stanford-Clark of IBM to link Oil Pipeline telemetry systems through satellite. It was once a proprietary protocol, but in 2010 MQTT was made available royalty-free, and in 2014 MQTT was made an OASIS standard. MQTT ...

Integrated Services Digital Network (ISDN)

Integrated Services Digital Network (ISDN) comprises communication standards facilitating the concurrent digital transmission of voice, video, and data over traditional public switched telephone network circuits. Unlike its predecessor, which primarily transmitted voice, ISDN’s innovation lies in integrating speech and data on the same lines, a capability absent in traditional telephone systems. Operating as a circuit-switched ...

History of Computer Network

Overview The world’s current population is around 7.6 billion people, and the number of devices connected to the internet is estimated to be over 50 billion, implying that each person uses approximately 6 internet-connected devices. This number has been increasing since the day when the first network, ARPANET was made. In today’s world, one cannot imagine life without the internet. In this article, ...
