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):
- Each character corresponds to a unique numeric value in the encoding table
- This numeric value is converted to a 2-digit hexadecimal representation
- The hexadecimal representations of all characters are combined to form the complete hexadecimal data
- 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 |
