ASCII Characters

Tags: Nomenclature and Symbols

ASCII stands for American Standard Code for Information Interchange.  Out of the 127 characters, the first 31 characters can not be printed, they are used for control, such as printers.  Codes 32 thru 127 are called printable characters. Only two can not be printed: 32 (Space) and 127 (Delete).  All the rest represent letters, numbers and symbols on the keyboard, which intern can end up as a printable word document.
