The Internet started with a simple idea – connecting computers together to share data in various ways. Since that humble beginning, people have started to connect more devices to the Internet. That’s the basis of the term Internet of Things (IoT). The Internet of Things extends internet connectivity beyond traditional devices like desktop and laptop computers, smartphones and tablets to an ever-growing network of everyday things that utilize embedded technology to communicate and interact with the external environment, all via the Internet. It’s the inter-networking of physical devices (“connected devices” and “smart devices”) that enable these objects to collect and exchange data.
The ‘thing’ in Internet of Things (IoT) could be any object that contains the required computing power & connectivity to the Internet and have the ability to collect and transfer data over a network without manual assistance or intervention. The embedded technology in the objects helps them to interact with internal states or the external environment, which in turn affects the decisions taken.
The ability to network embedded devices with limited CPU, memory and power resources means that Internet of Things (IoT) finds applications in nearly every field. Few examples,
