Internet of things (IOT):
Definition of IOT:
Internet of things (IOT) means physical devices connected to the internet which are able to interact, communicate and share the data collected by them with each other through the internet in order to make human life easier and automated.
The concept of a network of smart devices was discovered in 1982 at Carnegie Mellon University. a modified Coke vending machine was the first Internet-connected appliance. It was able to report its inventory whether newly loaded drinks were cold or not.
The term “Internet of Things” was coined by Kevin Ashton in a presentation to Proctor& Gamble in the year 1999. Ashton is a co-founder of MIT’s Auto-ID Lab. He also pointed that Radio-frequency identification (RFID) is essential to the IOT.
IoT is the extension of Internet connectivity into physical devices and everyday objects.
These devices contains Embedded electronics system with Internet connectivity and other hardware and sensors.
They can communicate and interact with others devices over the Internet, and they can remotely monitor and controll each other.
IOT has evolved due to the convergence of multiple technologies like machine learning, artificial intelligence, real-time analytics, commodity sensors, and embedded systems, wireless sensors, networks, control systems, automation and others all contribute to enabling the IOT.
IoT technology will be most important thing in feature automation.
The concept of the “smart home” involves devices and appliances such as lighting fixtures, thermostats, home security systems, automated door lock system smart speakers, TVs and other home appliances that support one or more common ecosystems, and can be controlled via devices associated with that ecosystem, such as smartphones and other hand gadgets like smart watch and fitness bands.
The concept of IOT has faced too much criticism. Especially in regards to privacy and security of users data. as the IOT devices share their data with each other. A hacker may hack a device and can missuse the data of users to harm them. So it is important to make the thing secure before giving them to a common user.
