ASCII, Hex, Hexadecimal, Octal, and Decimal are all very important number systems in computational technology. Computers are typically built to operate with these number systems because the basic components, operating in the binary numbering system map nicely into hexadecimal. The simplest way to map the binary numbers into human-readable text formats is with the ASCII (American Standard Code for Information Interchange) encoding. The binary encoding can be more concisely represented in hexadecimal, giving the more complex and capable human mind an advantage when visually inspecting the encodings used inside the computer.
