Description: The term ‘multi-device’ refers to systems or applications that can operate on multiple devices, which is especially relevant in the context of the Internet of Things (IoT). This capability allows different devices, such as sensors, actuators, computers, and mobile devices, to communicate and collaborate with each other to perform specific tasks. Interoperability is a key feature of the multi-device approach, as it enables users to access the same functionality and data from different platforms, whether it be a smartphone, tablet, or computer. Additionally, multi-device design promotes flexibility and scalability in IoT solutions, allowing businesses to adapt their systems to the changing needs of the market and users. In an increasingly connected world, where smart devices are an integral part of daily life, the ability to operate across multiple devices has become an expected standard for consumers and a necessity for software developers. This not only enhances user experience but also optimizes data and resource management in various environments.
