What Is IoT (Internet of Things)? A Complete Guide
Internet of Things (IoT) is among the most pivotal technologies of the modern digital world. Whether it's a smart watch, a home security camera, a connected car, a smart agriculture system or a machine in industry, IoT is reshaping the way that physical devices gather, share, and utilize information.
What, exactly is IoT?
In simple terms, IoT is the understanding of linking physical objects and devices with the web to gather information, interact with other devices or systems, and act on own or by minimal human interaction.
The use of IoT in homes, businesses, healthcare, agriculture, transportation, manufacturing, retail and more is commonplace today.
The Internet of Things is What?
The Internet of Things (IoT) is the name given to the network of physical devices that are outfitted with sensors, software, processors and communication technologies that enable them to be connected to networks and exchange data.
The IoT device may be a simple as a temperature sensor or a more complex such as a connected vehicle or industrial machine.
For instance, in a conventional light bulb, there's usually a switch that needs to be flipped. The smart IoT bulb is able to connect to a Wi-Fi network and be controlled via a smartphone. It can also be programmed to switch on and off automatically, depending on the system.
The Internet of Things is built upon this mix of devices, sensors, connectivity, software and data.
How Does IoT Work?
Typically an IoT system is comprised of multiple components that operate together.
