"NULL" (all caps) is a C preprocessor constant used to denote a null pointer. "NUL" (all caps) is sometimes used as an abbreviation for the null character. "Null" (uncapitalized except as appropriate for beginning a sentence) is an noun or adjective which can be used in a variety of contexts. You will note that "null" is never written in all caps in the Wikipedia articles you referenced. So a "NULL-terminated string" is a meaningless concept; you can't use a null pointer to terminate a character string. A "NUL-terminated string" is meaningful, as is a "null-terminated string" or "null-character-terminated string."
