An adaptive system is a framework that can adjust or modify its behavior according to the changes in its environment or circumstances. There are several other terms that can be used synonymously with adaptive system, such as dynamic system, flexible system, responsive system, and progressive system. These terms signify the capacity of the system to respond to the changing conditions and improve its performance by learning from its experiences. An adaptive system can be seen as a system that is capable of self-organizing, self-regulation, and self-adjustment. It is an essential characteristic of modern technology, particularly artificial intelligence, where systems are designed to learn and evolve over time, becoming increasingly efficient and effective in their operations.
