Internet of Things (IoT) refers to the interconnected network of physical devices, objects, and equipment embedded with sensors, software, and connectivity capabilities that enable them to collect and exchange data with each other and central systems over the internet.

Example
In human resources, IoT can be used to enhance workplace safety. For instance, wearable devices equipped with sensors can monitor employees' vital signs and movements in real time. If a worker's heart rate becomes unusually high or they fall, an alert is sent to the HR department, allowing for immediate response and potentially preventing accidents or health issues.
