Um byte string terminada em nulo (BNP) é uma sequência de bytes diferentes de zero seguido por um byte com o valor zero (o caractere nulo de terminação). Cada byte de uma seqüência de bytes codifica uma personagem de algum conjunto de caracteres. Por exemplo, a matriz de caracteres {'\x63','\x61','\x74','\0'} é um BNT segurando a corda "cat" na codificação ASCII.

Original:

A null-terminated byte string (NTBS) is a sequence of nonzero bytes followed by a byte with value zero (the terminating null character). Each byte in a byte string encodes one character of some character set. For example, the character array {'\x63','\x61','\x74','\0'} is an NTBS holding the string "cat" in ASCII encoding.
