* Data structures or algorithms: If you're studying computer science, it might refer to data that cannot be processed or accessed in any order without affecting the result. This is relevant in parallel processing or certain types of database queries. However, this wouldn't be directly related to Penn State itself, but rather to concepts used in studying there.
* Transportation: It *might* be informally used to describe information relevant to non-commuting students (those who don't live near the campus and travel long distances). This could include details on housing, transportation options, or support services for such students. But this is highly speculative.
* A typo or misunderstanding: There might be a typo in the original phrase, or it's being used in a non-standard way.
