Fun Fact
Hexadecimal is base-16 numbering, meaning it uses sixteen symbols instead of ten. Programmers love hex because one byte can be neatly represented using exactly two hexadecimal digits.
Historical Context of ASCII and Hex
ASCII was developed in the 1960s as a universal standard for representing text in computers. As computing evolved, hexadecimal became a convenient way to express binary data in a human-readable form. Converting ASCII to hex has been a fundamental technique in software engineering, networking, and digital electronics for decades, and it remains essential in modern technology.
