ASCII Code

ASCII:

ASCII is short for American Standard Code for Information Interchange, and is a 7 bit encoding of characters on computers. There are 128 values ranging from 0 to 127, of which 95 are printable characters and 33 are not visible but used for control characters.

There are several larger character sets that use 8 bits known as ASCII-8, which gives them 128 additional characters. The extra characters are used to represent non English characters, graphics symbols, and mathematical symbols.
