ASCII text to hexadecimal conversion examples
ASCII
ASCII is an encoding system, which is an abbreviation for the American Standard Code for Information Interchange. Designed earlier for old-type computers and printers that use telegraphic codes. It was designed from 128 symbols including 10 numbers, a number of punctuation marks, 26 letters of the English alphabet, etc.
Hex System
Hex or hexadecimal is a number system with a base 16. This number system is especially interesting because in the decimal number system we have only 10 digits to present the numbers. As the hex system has 16 digits, the first 6 letters of the English alphabet used to represent extra 6 digits. So, hex digits are 0,1,2,3,4,5,6,7,8 and 9 A, B, C, D, E, F.
