Not so long ago, the most widely used character encoding was ASCII. This was a character encoding based on a one-byte-per-character approach, where one byte contained 7-bits. The 7-bits allowed for a grid of 128 possible numbers, each of which could be used to represent a different character. Some numbers were associated with control codes, and the graphical characters in the set comprised the English alphabet and a number of symbols.
