1.
NULL - n., adj. - signifying the absance of data. Things such as character strings, and various types of numeric values can be described as "NULL" when they contain no data. (shadow:light::NULL:data)
ex.1:
<faceprint> we returned js->roomlist without setting it, so it was NULL

ex.2:
(In C++:
void function()
{
int variable;
}

'variable' would have a value of NULL until it is initialized, and 'function' would return NULL because it was created with a 'void' data type.)

ex.3:
"Your sister is soooo stupid, it's like she's NULL between the ears..."

Unfortunately nobody can be told what the NULL is…
NULL is the value that we can not define. This is special value used in db that is given to the field when no value was assigned. In practical life we can consider it as no value. It is not zero, it is not letter or any other character this is something that can not be used.
