ASCII
- ASCII is an acronym for the American Standard Code for Information Interchange
- ASCII is used to represent English characters as numbers with each letter assigned a number from 0 to 127 (= 128 possibilities).
- Computers converts text to numbers because it makes it possible to transfer data from one computer to another.
- The standard ASCII character set uses 7 bits (27 = 128 possibilities) for each character (English).
- There are other character sets for example ISO8859 or Unicode using 8 or more bits to convert non-English characters and other symbols to numbers.
