XML (eXtensible Markup Language)

XML, or eXtensible Markup Language, is a flexible text format used to store and transport data. It allows users to define their own tags, making it easy to represent complex information in a structured way. Think of XML as a way to organize data in a clear, hierarchical format, much like how folders and files are organized on a computer. It is widely used in web services, data exchange, and configuration files, enabling different systems to communicate and share information efficiently while maintaining readability for both humans and machines.
