XML (Extensible Markup Language)
Extensible Markup Language (XML) is a flexible text format used to create structured documents by encoding data in a format that is both human-readable and machine-readable. XML allows developers to define custom tags, facilitating the sharing of structured data across different information systems, particularly via the internet. It is widely used in web services, configuration files, data exchange between applications, and more. XML provides a platform-independent way of representing data, making it essential for interoperability in diverse computing environments.
