The term "ubiquitous" refers to something that is present or found everywhere at the same time. It describes the quality of being widespread or constantly encountered in various environments. For example, in today's digital age, smartphones have become ubiquitous, as they are used by people across the globe for communication, information, and entertainment. In technology, the concept of ubiquitous computing involves integrating computing devices into everyday objects and environments, making technology seamlessly available. This can be seen in smart homes, where devices like smart speakers and thermostats are interconnected and accessible from anywhere, enhancing convenience and efficiency in daily life.
