Internet of Things (IOT)

Internet of things

Internet of things

It is the ability to transfer data over a network without any human-to-human or human-to-computer interaction. A system of interrelated computing devices, digital and mechanical machines, objects, etc. which contains unique identifiers(UIDs). IoT covers the concepts of Smart Homes which include devices and appliances such as lighting systems, thermostats, home security systems, etc. Such devices and appliances are controlled by smartphones and smart speakers which are linked wirelessly or with wires.

IoT in action - Towards Data Science


The term IoT was first coined by Kevin Ashton of Procter & Gamble in 1999. But the concept of a network of smart devices was first discussed in the year of 1982. A modified coke vending machine at Carnegie Mellon University became the first internet-connected device. The machine was able to tell whether the machine was loaded or not and whether the drinks in the machine were cold or not.

MOSFET(metal-oxide-semiconductor field-effect transistor, or MOS transistor) is the driving force behind the concept of IoT. Mohamed M. Atalla and Dawon Kahng invented MOSFET in 1959. MOSFET is the basic building block in most of the modern-day electronic items such as computers, mobile phones, tablets, etc.

Applications of IoT:

IoT has an extensive set of applications that are classified as consumer, commercial, industrial and infrastructure applications.

Consumer Applications:

Consumer applications include smart home and eldercare. A smart home consists of all the appliances which make it easier for the residents to do various tasks without doing it physically. Smart lighting, voice automated devices, home security systems, surveillance cameras, etc. are various devices which helps in making a normal home a smart home. Eldercare is a sub-application of Smart Homes. it assists those who have disabilities and elderly people. Amazon Echo, Google Home, Apple’s Homepod And Samsung’s SmartThings Hub are the most widely used devices in a smart home.

Problems related to IoT:

The main purpose of IoT is to ease our lives to the next level. But with these advancements, IoT has brought some problems with it. Firstly, IoT has widened access to information which has led to danger to the privacy of people. Secondly, data stored in the databases are not safe which endangers the security of people. Moreover, people can hack these data from the databases.

In conclusion, I Would like to say that IoT is a great step towards the future and developing mankind. Just like the internet, there are somethings which you can’t resist. Sooner or later, you have to accept them.
