Final Answer:
A set of programs that allow data to be exchanged on a website without changing the website's display is AJAX.
Thus the correct option is (B).
Step-by-step explanation:
AJAX, which stands for Asynchronous JavaScript and XML, is a set of programs that enables data exchange on a website without altering the website's display. AJAX allows web pages to dynamically update content by asynchronously sending and receiving data in the background, without requiring a full page refresh. This technology is crucial for creating responsive and interactive web applications.
Unlike Java, HTML, and Swift, AJAX is not a programming language on its own but rather a combination of technologies, including JavaScript for handling asynchronous requests and XML or JSON for data interchange. It enables a smoother user experience by allowing web applications to fetch data from a server and update parts of a page without reloading the entire content. This enhances the interactivity and responsiveness of modern web applications.
In summary, AJAX plays a vital role in web development by facilitating seamless data exchange on websites, enhancing user interactions, and providing a more dynamic and engaging user experience. The correct choice from the given options for a set of programs enabling non-disruptive data exchange is (b) AJAX.
Thus the correct option is (B).
