What is null in programming?
In computer programming, null is both a value and a pointer. Null is a built-in constant that has a value of zero. It is the same as the character 0 used to terminate strings in C.

What does null mean in a password hash?
I assume you mean NULL in the SQL sense, as an undefined value. If the system compares the hash of the user-entered password with the stored hash, as it should, then an undefined value (or even an empty string) would never match. Similarly, the stored hash could be set to some other string that will never match as a valid password hash.
Is there a way to set a password that never matches?
Similarly, the stored hash could be set to some other string that will never match as a valid password hash. On Linux systems, you can see system accounts in /etc/shadow with a * in the place of the password hash, and locking a user with usermod -L sets the hash to !.
