## Information and Primary Use

Null character is a Control Character with no value/zero value, it in listed in many character sets, and is available in most mainstream programming languages. It is commonly abbreviated NUL or NULL (as it's actual name is Null Character). in 8-bit codes, it happens to be known as Null byte.

The meaning of null is perplexed, it's original meaning was like No Operation (which isn't listed due to it not being a Unicode Character), in which is had no meaning when sent to a printer or terminal, sort of like a blank character that has no real meaning, in some terminals it is rendered as a space, it is defined as a C0 or C1 control code When electro-mechanical teleprinters were used as computer output devices, one or more null characters were sent at the end of each printed line to allow time for the mechanism to return to the first printing position on the next line (though not confirmed to be true). On punched tape, the character is represented with no holes at all, so a new unpunched tape is initially filled with null characters, and often text could be "inserted" at a reserved space of null characters by punching the new characters into the tape over the nulls.

The present meaning (while can still be used as it's old) is more used in C (The Programming Language) and it's other forms or derivatives and in other data formats, where it serves as a reserved character used to signify the end of a string, normally called a null-terminated string. This allows the string to be any length with only the overhead of one byte; the alternative of storing a count requires either a string length limit of 255 or an overhead of more than one byte, for more information, see The Wikipedia Article on Null and The Wikipedia Article on Null-Terminated string however this is only in programming languages (mostly C) and is normally never used on normal language and code.

Some people whose name is Null have experienced problems with computer systems.
