What is the value of null in ASCII?
NUL (null) has a value of zero and causes a printer or display to ignore the character. Others characters were once used to give information about messages, for example STX (start of text, 0x02,) and ETX (end of text, 0x03). Computers often have a need to store groups of characters (forming words or sentences).
