ASCII (American Standard Code for Information Interchange) is a 7-bit characters code, with values from 0 to 127. The ASCII code is a subset of UTF-8 code. The ASCII code includes control characters and printable characters: digits, uppercase letters and lowercase letters. ...
The ASCII code for the lowercase letter 'a' is 61H in hexadecimal. To find the ASCII code for the lowercase letter 'd', we add 3 to the ASCII code of 'a' since 'd' comes three letters after 'a' in the alphabet. This gives us 64 in decimal, which is 40 in hexadeci...

Jimenez-Sanchez introduced the term “tyte” (tetramer byte) and proposed to apply ASCII code for conversion letters and some symbols into tetraplets (Jimenez-Sanchez, 2013). The use of 95 tetraplets encoded the upper- and lowercase letters of the English alphabet (52 codons) and other text ...
