Machine language: Conversion between Hexadecimal, Binary and Decimal

In computing and digital electronics, the use of the traditional decimal system (base 10) is inefficient for understanding how data flows in memory. Programmers and system administrators must master converting between Binary (base 2) and Hexadecimal (base 16) systems.

Computer numerical systems

• Binary (Base 2): The pure state of silicon. Made up of zeros and ones that represent the passage or blocking of electric current.
• Decimal (Base 10): The standard human system.
• Hexadecimal (Base 16): The elegant intermediate form. Use the digits 0 to 9 and the letters A to F.

Hexadecimal is very valuable because it allows long, hard-to-read binary strings to be summarized by humans into compact, readable formats (for example, when defining CSS web colors or physical memory addresses).
