Question

Quizplus · Accepted Answer

XML is a text-based format, which means that it can be easily transmitted over networks, including the Internet, through firewalls without causing any issues. Firewalls typically rely on blocking certain types of files or traffic based on their file extensions or other identifying characteristics, but since XML is just text, it can easily pass through these security measures. This is one of the reasons why XML is such a popular format for data exchange between different systems and applications.
