The Internet of Things (IoT) describes a network of physical objects such as devices, vehicles or houses with the Internet. These objects are given a unique identity/address in the network and are linked interoperably over the Internet via software or sensors. With the Internet of Things, tasks can be carried out fully automatically. For this reason, the intelligent devices are also referred to as "smart devices". In contrast to Industry 4.0, IoT also includes the private domain such as smart home applications. The devices can communicate with each other (Machine-to-Machine communication/M2M) or can be controlled by a user from any location via an interface on the Internet. The smart devices are used to supply information, for automated orders, as well as for automatic emergency call systems.
