A. ENGAGE
1. XML (Extensible Markup Language) is a markup language
that defines a set of rules for encoding documents in a format that is both
human-readable and machine-readable. It provides a standardized way to
structure and store data, making it easy to exchange information between
different systems and platforms.
XML uses tags to define elements, similar to HTML, but
unlike HTML, XML does not have predefined tags. Instead, users define their own
tags to create a hierarchical structure for the data.
2. JSON (JavaScript Object Notation) is a lightweight data
interchange format that is easy for humans to read and write and simple for
machines to parse and generate. It is widely used for transmitting data between
a server and a web application, as well as for storing and exchanging
structured data.
JSON data is represented as key-value pairs and organized
into objects and arrays.
3. AJAX (Asynchronous JavaScript and XML) is a set of web
development techniques that allows for asynchronous communication between a web
browser and a server. It enables the retrieval and updating of data on a web
page without requiring a full page reload. AJAX leverages a combination of
technologies, including JavaScript, XML, and more commonly, JSON.
