Hexadecimal Basic Knowledge

What is Hexadecimal

Hexadecimal is a numeral system with base 16, using the digits 0-9 and A-F (or a-f) to represent values. In computer science, hexadecimal is often used to simplify binary number representation because 4 binary digits correspond exactly to 1 hexadecimal digit.

Hexadecimal is widely used in programming, network protocols, memory address representation and other fields, as it is more readable than binary while being closer to the underlying data representation of computers than decimal.

Hexadecimal Application Scenarios

  • Memory address representation in computer programming
  • File format analysis and debugging
  • Network protocol data representation
  • Image and color value representation (such as color codes in HTML)
  • Encryption algorithms and secure communication
  • Low-level system programming and hardware interaction

Hexadecimal and Text Conversion Principle

Text to hexadecimal conversion is usually implemented through character encoding tables (such as ASCII, UTF-8):

  1. Each character corresponds to a unique numeric value in the encoding table
  2. This numeric value is converted to a 2-digit hexadecimal representation
  3. The hexadecimal representations of all characters are combined to form the complete hexadecimal data
  4. Hexadecimal to text is the reverse of this process

Hexadecimal Conversion Examples

Here are simple examples of text and hexadecimal conversion:

Character ASCII Value Hexadecimal Representation
A 65 41
B 66 42
C 67 43
1 49 31
Space 32 20
