The Internet of Things (IoT) is more than a buzzword; it is a system that is influencing how humans interact with technology, and how human beings behave. The meaning of IoT is connecting systems and devices that, until now, haven’t been connected. In other words, IoT is bestowing digital intelligence on otherwise dumb things. With an IoT smart home security system, a homeowner can lock or unlock their front door from a phone, adjust their home’s temperature or operate a security camera to see who is knocking at their door. Today, IoT applications in Business can be found everywhere. Smart cars inform humans of the fastest or shortest route based on traffic and adjust driving based on weather conditions. The human-machine interface is rapidly changing, thanks in large part to the Internet of Things. IoT is a vast network of sensors and systems that include everything from smartwatches and smartphones to smart cars, barcodes on boxes and heating and air conditioning units. But, what does the Internet of Things (IoT) mean?
Literal IoT definition
IoT stands for the Internet of Things. However, that doesn't explain much. It helps to define IoT, even briefly. The IoT is made up of things or devices connected by the internet that can take in information and talk to each other, sharing information back and forth. The connected things use sensors to absorb the information. The sensors input data into a large, intelligent system comprised of smaller smart systems. In reality, IoT is far more complicated than that.
Expanded IoT definition
The expanded definition of IoT is the upgrade of mobile, home and embedded applications to become part of a network of connected physical devices that all have sensors that both import and export data. The devices, using embedded sensors, gather data about the environment in which they are operating and how they are being used. The sensors are integrated into every physical device from electrical appliances (fridges, stoves, furnaces) to lights (home lighting, traffic lights, car lights) to smartphones and tablets (TVs too) to barcodes on non-electrical items (pill bottles, boxes). The devices then share the data in real time about their operational state through the Cloud to an IoT platform where there is a universal language by which all IoT devices communicate. The gathered data is then dumped, or integrated, and data analytics is performed.
Data analytics is drawing valuable insights and information from masses of raw data. Data analytics is now mostly automated, with algorithms performed by Artificial Intelligence (AI) software that clean, sort, and generally make sense of the vast amounts of data that IoT devices provide. With a far higher capacity for computation than humans, Internet of Things technologies can analyze in enormous amounts of data in seconds. Valuable information and insights are then pulled from the data without the aid of human beings. The information is then shared with human users and other IoT devices.
The Internet of Things creates an extensive system of information, comprised of smaller systems of information; smart devices are connected to smart home systems which are connected to smart city systems. Significant changes come when data from one end of a large system of systems, to the other end of a large system, can be analyzed. Through the mass sharing of information from other devices, an extensive network of data is created that benefits and betters all user experiences. The Internet of Things leads to better healthcare outcomes, more efficient manufacturing, optimizing energy production and consumption, more effective use of natural resources and lowered waste production in addition to a host of other benefits.
