Industrial IoT (IIoT) refers to the application of IoT technology in industrial settings, such as manufacturing plants, oil and gas facilities, and power plants. IIoT devices, such as sensors and actuators, can collect and analyze data related to equipment performance, production processes, and energy consumption, enabling companies to optimize their operations and improve efficiency.
How IoT works
IoT architecture
The architecture of IoT consists of three main components: devices, networks, and data. Devices refer to physical objects that are equipped with sensors, actuators, and other hardware that allows them to collect and transmit data. These devices can range from simple temperature sensors to complex industrial machines.
Networks are the systems that allow devices to communicate with each other and with other systems. There are several types of networks used in IoT, including wired and wireless networks, and each has its own advantages and disadvantages.
Data is the information that is collected by devices and transmitted over networks. This data can be used to gain insights into the state of the device, the environment, or the system as a whole. The data can also be used to control the device or to trigger actions based on certain conditions.
IoT devices
IoT devices are typically classified into two categories: those that are connected to the internet and those that are not. Devices that are connected to the internet are known as “smart” devices and include things like smartphones, smart home appliances, and smart cars. These devices are equipped with sensors and other hardware that allows them to collect and transmit data.
Devices that are not connected to the internet are known as “dumb” devices and include things like traditional home appliances, industrial machines, and medical devices. These devices do not have the ability to collect and transmit data, but they can still be controlled by smart devices through the use of interfaces like Bluetooth or Wi-Fi.
IoT networks
IoT networks are the systems that allow devices to communicate with each other and with other systems. There are several types of networks used in IoT, including wired and wireless networks. Wired networks use physical cables to connect devices, while wireless networks use radio waves to transmit data.
Wired networks are typically used in industrial and commercial settings where the devices are in close proximity to each other. Wireless networks are used in a wide range of applications, including smart homes, wearable devices, and connected cars.
IoT data
IoT data is the information that is collected by devices and transmitted over networks. This data can be used to gain insights into the state of the device, the environment, or the system as a whole. The data can also be used to control the device or to trigger actions based on certain conditions.
The amount of data generated by IoT devices is growing rapidly, and it is estimated that by 2025 there will be over 75 billion IoT devices in use worldwide. This data is being used in a wide range of applications, including smart cities, healthcare, and manufacturing.
IoT applications
IoT applications are the ways in which IoT technology is being used in different industries and sectors. Some of the most common applications of IoT include:

IoT vs. Traditional Computing
Differences between IoT and traditional computing
Scope
The Internet of Things (IoT) and traditional computing differ in terms of their scope and capabilities. While traditional computing is limited to devices such as desktops, laptops, and servers, IoT encompasses a much broader range of devices, including smart home appliances, wearable technology, and industrial machinery. This means that IoT has the potential to connect and integrate a vast array of devices, making it a much more extensive system than traditional computing.
IoT vs. traditional computing: A comparison
One of the key differences between IoT and traditional computing is the level of connectivity and interaction between devices. Traditional computing relies on a centralized system where devices are connected to a central server or computer, while IoT enables direct communication between devices without the need for a central hub. This decentralized approach allows for more efficient and seamless communication between devices, as well as greater flexibility and scalability.
IoT vs. traditional computing: The key differences
Another important difference between IoT and traditional computing is the type of data that they handle. Traditional computing systems typically store and process structured data, such as text and numbers, while IoT deals with both structured and unstructured data, including sensor readings, images, and audio. This ability to handle unstructured data makes IoT more versatile and adaptable to a wider range of applications.
Overall, the main differences between IoT and traditional computing lie in their scope, level of connectivity, and data handling capabilities. While traditional computing is limited to specific devices and centralized systems, IoT offers a much more extensive and flexible approach to connectivity and data handling, making it a powerful tool for a wide range of applications.
