About ASCII

ASCII is a 7-bit character encoding standard that maps the values 0 through 127 to letters, digits, punctuation and control signals. It remains relevant because many protocols, formats and legacy systems build on top of ASCII-compatible text.

Examples

32  = 0x20 = Space
65  = 0x41 = A
10  = 0x0A = Line Feed
