Question

Which of the following technology is used for exchange of data between different systems ?

• A. Extensible markup language
• B. Hypertext markup language
• C. Dynamic Hypertext markup Language
• D. Practical Extraction and Reporting Language

Answer 1

Answer:

A. Extensible markup language

• Extensible Markup Language (XML) is specifically designed to store, transport, and structure data so it can be easily shared and understood across completely different software applications, operating systems, and hardware platforms.

Why the other options are not used for system-to-system data exchange

• Hypertext Markup Language (HTML): Used to format and present content visually in a web browser for human users, not for direct data exchange between systems.

• Dynamic Hypertext Markup Language (DHTML): A combination of HTML, CSS, and JavaScript used to create interactive and animated websites on the client side.

• Practical Extraction and Reporting Language (Perl): A high-level programming language used for text processing, script automation, and web development, rather than a data exchange format itself.
