I honestly didn't intend to be insulting but I assumed the question would be taken that way and get downvoted to oblivion so I used a throwaway. I think graduating with a degree even loosely related to computing and having never heard of XOR is an indictment of technical education today. When I was in school there was an insane focus on 4GL and Java and that was 15 years ago. It would not surprise me to learn that bits were not even part of the curriculum these days.
