The Internet of Things (IoT) is no longer something that will come in time. It will likely be a significant part of our life, many everyday tasks easier. But what is IoT? As Eric Schmidt, the president of Google at the WEF (World Economic Forum), said, the IoT “will always be part of our presence”. People will live with the IoT without becoming aware. Several types of devices will monitor our movements and actions, even without any interaction on our part. By 2020, likely more than 26 billion devices will be connected.
