    "Null" is a term of art in law, mathematics, and philosophy.

  • Null is not just a computer science word. It's used in other context, for instance the stock phrase "null and void" - meaning that the referrent no longer has any effect. Nor is NULL in CS necessarily zero: it's a pointer value that can't point to a valid address, so it could be implemented as e.g. all ones in binary - and that would be IMHO a lot more practical, since 0 is a valid address.

    And nought has many uses besides just for referring to the digit "0" (which specific usage is moreover alien to American English). See these in Shakespeare, for instance. Jun 16, 2015 at 21:31

    "Null" is the German word for zero.. If your teacher, or his teacher, was Germain, you may use "null" for zero. "Nought" used for zero is more common in the UK than in the US.

    Nought is an old form of nothing and now can also refer to the digit (as does ought, even though it's not negative). Null and zero refer to the digit. Jun 16, 2015 at 23:24
