What term refers to documentation created in addition to the software application, such as library and user documentation?

• A. Internal documentation
• B. External documentation
• C. Primary documentation
• D. Secondary documentation

Answer: (B)

External documentation is the set of materials created to accompany a software product for people outside the development team. It sits outside the code and is meant for end users and external developers. Examples include user guides, installation manuals, and library or API documentation. This distinguishes it from internal documentation, which targets the internal team and is typically embedded with the code or kept in the project repository (like code comments and internal design notes). Primary and secondary documentation aren’t standard labels for this context, so they don’t fit as well as external documentation.
