Internet was used mainly by humans for information interchange and interaction.This can be called the internet of the people.Internet of things on the other hand is a collection of things.
Things can be a vast array of things such as smart phones,embedded devices,smart watches etc.
Internet of things means that the devices are communicate with each other using wireless network (or internet).sensors are embedded in the devices or things.These sensors collect data and the different devices communicate with each other.In short embedded devices are connected to the internet ,hence the name internet of things.
Internet Of Things is a concept which means interconnection of devices over internet where each device is assigned a unique address.
This is such a an revolutionary concept because instead of different devices existing in isolation they can now be a part of a large interconnected network and can access different devices on the network. IoT devices usually have sensors to collect data and can communicate to other IoT devices.
IoT devices could be useful in different areas from healthcare to real time applications.
The Thing here can refer to different variety of devices.These devices can vary from washing machines to automobiles with sensors.Since these devices utilize internet to connect to each other so unique IP address needs to be assigned to each device.
IPIv6 which is the latest version of Internet Protocol has increased address space that can be used to assign unique address’ to devices .This means that practically every possible device can be a part of Internet of Things
Since devices uses internet to connect with each other,they use standard technologies instead of proprietary ones.The Internet Engineering Task Force (IETF) is one such organization that develops internet standards and is working on developing common standards for IoT .So every device can communicate using common standards.
IoT is expected to be the next big transformation since the arrival of internet.
