American Standard Code for Information Interchange was designed in 1960 for use in 7bit teleprints, and based on previous telegraph code. It was last revised in 1986, and late incorporated into the Unicode standard.
The first character codes are known as "control codes" and they were used to control hardware operations. Most of those codes are no longer used for their exact original purpose, but some are still in common use, namely:

NUL (0) is the string terminator for C strings, it marks the end of a string.
TAB (9) is still used widely to indicate tabulations in plain text.
CR (13) and LF (10) are used to indicate the end of line, with Window software using both CR and LF, and Linux/Unix using just LF.
