AJAX stands for Asynchronous JavaScript and XML. This term describes a set of web development techniques that allows web applications to communicate with a server asynchronously in the background, meaning that a web page can update content without requiring a full page reload. This is achieved using JavaScript, which allows for dynamic updates and user interactions, and XML (though nowadays JSON is more commonly used) to send and receive data.

The term highlights the key elements involved in this technique: "Asynchronous" refers to the ability to perform operations in the background, "JavaScript" is the programming language used to create the client-side interactions, and "XML" refers to the format traditionally used for data exchange. However, the flexibility of AJAX allows developers to utilize other formats as well, such as JSON, enhancing its practicality in modern web development. This foundational understanding of AJAX is vital for creating responsive web applications.
