I just over heard a 4th year CS major at Tech ask another 4th year CS major: "Whats a DLL?"

The 2nd one said "I don't know."

I piped up across row saying "Its a library of code that you can use, normally supplied by Microsoft."

The 1st says "... ... OH! So its like a Class File! In Java"

Yes. This person was a 4th Year CS major, who has a 3.4.
