What is IOT ? Explain components in IoT.

Internet of Things (IoT) is an ecosystem of connected physical objects that are accessible through the Internet (formal definition). So, in simple terms IOT means anything that can be connected to internet and can controlled / monitored using internet from our smart devices or PCs. The “things” specified here can be anything from small tracking chips to actual smart cars on road all these can be categorized as IOT. All things that are connected to internet are assigned with ip to it so that it can be monitored uniquely using internet. The embedded systems and technology are the objects that help in realization of successful IOT. Major Components of IOT: Things or Device - These are fitted with sensors and actuators. Sensors collect data from the environment and give to gateway where as actuators perform the action (as directed after processing of data). Gateway - The sensors give data to Gateway and here some kind pre-processing of data is even done.It also acts as a level of security for the network and for the transmitted data. Cloud - The datas after being collected at is uploaded to cloud. Cloud in simple terms is basically a set of servers connected to internet 24*7. Analytics - The data after being received in the cloud processing is done . Various algorithms are applied here for proper analysis of data .(techniques like Machine Learning etc are even applied) User Interface - User end application where user can monitor or control the data.
