What Is the Internet of Things

This is a concept that is used daily in the world of technology, but not everyone really knows what that term means. Basically this idea is about the digital interconnection of everyday objects with the Internet. In case that everyday objects had identifiers such as radio labels, they could be identified and managed by other equipment, just as it is done by humans. For example, if books, kits, lamps, among other items, were connected to the Internet and equipped with identification devices, surely there would be nothing out of stock, and we would know exactly where these articles can be found, how and where people purchase and consume these and other products around the world.

This idea was created in 1999 by Kevin Ashton, through research in the field of RFID and sensor technology. Currently there are various devices connected to the Internet, such as smartphones, tablets, laptops and even televisions. But in the world there are a huge number of objects with which we interact daily. The aim, through the internet of things, is to achieve global connectivity with these objects through the Internet and can manage them using a given device. It is expected that by 2020 there could be about 26 billion objects connected through this system.
