Why it is called as the Internet of Things

 

1. 1.      What is Internet of Things : “Sensors and actuators embedded in physical objects are linked through wired and wireless networks”. 

   2.      The term Internet of Things was invented in 1999, initially to promote RFID technology

   3.      M2M or the Industrial internet are not opposing concepts to the Internet of Things.The popularity of the term IoT did not accelerate until 2010/2011 and reached mass market in early 2014

Birth of Internet of Things

Kevin Ashton, the Executive Director of Auto-ID Labs at MIT, was the first to describe the Internet of Things, while making a presentation for Procter & Gamble. During his 1999 speech, Mr. Ashton stated:

“Today computers, and, therefore, the Internet, are almost wholly dependent on human beings for information. Nearly all of the roughly 50 petabytes (a petabyte is 1,024 terabytes) of data available on the Internet were first captured and created by human beings by typing, pressing a record button, taking a digital picture or scanning a bar code. The problem is, people have limited time, attention, and accuracy. All of which means they are not very good at capturing data about things in the real world. If we had computers that knew everything there was to know about things, using data they gathered without any help from us, we would be able to track and count everything and greatly reduce waste, loss and cost. We would know when things needed replacing, repairing or recalling and whether they were fresh or past their best.”

History of Communication system

In the communication fields, the history starts with the   Samuel Morse’s telegraph communication. It gave the revaluation in the communication field.  He transmitted  the “What hath God wrought,”  word in electric telegraph between Washington, D.C., and Baltimore, Maryland, in 1844, a completely revolutionary means of real-time, long-distance communications was triggered. It was formulated by manual form in variable length code. Specifically, the Morse code is a variable-length code using an alphabet of four symbols: a dot, a dash, a letter space, and a word space; short sequences represent frequent letters, whereas long sequences represent infrequent letters.

Lets play with Kahoot tool - A tool for technical subject to make online Quiz in game model

Todays Educational system has been moved towards the online platform. To engage the students effectively and make them interesting to learn, we need to move online platform and effectively use it. 

Here  i listed some useful website and the links. 

Kahoot tool- https://kahoot.com/ .  It is very useful tool to make the online class more interactive. Pros: We can set the time for each question . 

Kahoot is a highly interactive way to assess knowledge using a game format. 

 Students To attend the Quiz use www.Kahoot.it and enter the PIN. 

The pin number is generated when Quiz started in faculty login. 

We have to share the pin to students and ask them to enter in https://kahoot.it/ .

 Eg: use this link to attend model quiz
