"Responsive" refers to the ability of a system or design to adapt to different conditions or inputs. In technology, it often describes websites that adjust their layout and content based on the size of the screen being used, such as a computer, tablet, or smartphone. This ensures that users have a good experience regardless of the device they are using. In a broader context, "responsive" can also apply to people or organizations that react quickly and positively to requests or changes. For example, a customer service team that promptly addresses inquiries is considered responsive, as they meet the needs of their clients effectively.
