The term Internet of Things generally refers to scenarios where network connectivity and computing capability extends to objects, sensors, and everyday items not normally considered computers; thus, allowing these devices to generate, exchange and consume data with minimal human intervention. There is, however, no single universal definition.
The concept of combining computers, sensors, and networks to monitor and control devices has existed for decades. However, the recent confluence of several technology market trends is bringing the Internet of Things closer to widespread reality.
Medical and healthcare
Building and home automation
Trends and characteristics-
The IoT's major significant trend in recent years is the explosive growth of devices connected and controlled by the Internet.The wide range of applications for IoT technology mean that the specifics can be very different from one device to the next but there are basic characteristics shared by most.
Ambient intelligence and autonomous control are not part of the original concept of the Internet of things. Ambient intelligence and autonomous control do not necessarily require Internet structures, either.
