American Standard Code for Information Interchange (ASCII)
The standard code, using a coded character set consisting of 7-bit coded characters (8-bits including parity check), that is used for information interchange among data processing systems, data communication systems, and associated equipment. The ASCII set consists of control characters and graphic characters.

ASCIIZ
A string of ASCII characters that is terminated with a byte containing the value 0.
A string of (n+1) characters where the (n+1)th character is the "null" character (X'00') and is used to represent a n-character string with implicit length. Also called a "zero-terminated" string or an "ASCIIZ" string.
