XML? JSON? AJAX?
A. XML The markup language XML (Extensible Markup Language) offers a set of rules for encoding texts in a human- and machine-readable manner. In contrast to HTML elements, which are used to show data, XML is used to store and organize data rather than prescribing how it should be shown. B .JSON JSON (JavaScript Object Notation) is a straightforward data exchange standard. Reading and writing are easy for humans. It is simple for machines to parse and produce. This word is typically used when data is transferred from a server to a web page. C. AJAX AJAX (Asynchronous JavaScript and XML) is a collection of client-side web development approaches for creating asynchronous online applications. Web applications may use Ajax to transmit and receive data from a database.
