IoT stands for Internet of things (IoT) is the network of physical devices, vehicles, home appliances and other items embedded with electronics, software, sensors, actuators, and connectivity which enables these objects to connect and exchange data.
The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
Each thing is uniquely identifiable through its embedded computing system but is able to inter-operate within the existing internet infrastructure.
The IoT allows objects to be sensed or controlled remotely across existing network infrastructure, creating opportunities for more direct integration of the physical world into computer-based systems, and resulting in improved efficiency, accuracy and economic benefit in addition to reduced human intervention.
The Internet of Things is simply “A network of Internet connected objects able to collect and exchange data”.
The word “Internet of Things” has two main parts; Internet being the backbone of connectivity, and Things meaning objects / devices .
In a simple way to put it, we have “things” (things are nothing but your embedded system devices) that sense and collect data and send it to the internet. This data can be accessible by other “things” too.
In generalized form, IoT = ET + NT + IT
At the simplest level, IoT is a combination of Embedded Technology (ET), Network Technology (NT) and Information Technology (IT)..
Let me give you a practical example. Lets imagine you have a “Smart air conditioning unit” in your home that is connected to the internet. (This is a “thing” connected to the internet) Now, imagine it’s a hot summer day and you have left for home from your work. You would like your home to be cool enough by the time you enter it. So, when you leave from your office, you can remotely switch ON the air conditioning unit of your home using your mobile (another “Thing” connected to the internet). Technically, with internet, you can control your AC system from any part of the world as long as both the AC and your mobile are connected using the “Internet”.
Experts estimate that the IoT will consist of about 30 billion objects by 2020.
It is also estimated that the global market value of IoT will reach $7.1 trillion by 2020
