Why Programmers Must Understand Base Systems
Computers operate fundamentally on binary (Base 2)—meaning high and low electrical voltages represented as 1s and 0s. However, reading thousands of binary digits is incredibly difficult for humans. Hexadecimal (Base 16) provides a compact, human-readable shorthand to represent binary strings.
Every block of four binary digits (bits) translates exactly to one hexadecimal character, making base conversions highly useful for memory addresses, network masks, and color codes.
Quick Reference Base Table
Here is how numbers align across Decimal, Binary, and Hexadecimal:
| Decimal (Base 10) | Binary (Base 2) | Hexadecimal (Base 16) |
|---|---|---|
| 0 | 0000 | 0 |
| 5 | 0101 | 5 |
| 10 | 1010 | A |
| 15 | 1111 | F |
