Quick Examples

Number Systems & Binary Guide

Understanding Binary

Binary uses only 0 and 1 (base 2)
Each digit represents a power of 2
Computers store all data in binary
8 bits = 1 byte = 1 character
ASCII maps characters to numbers

Practical Applications

Binary: Computer programming, data storage
Hex: Color codes, memory addresses
Octal: File permissions in Unix/Linux
Decimal: Human-readable numbers

Conversion Examples

A = 01000001 (binary)
A = 41 (hex)
A = 101 (octal)
A = 65 (decimal)
All represent the same character

Tips & Tricks

Binary is most common in programming
Hex is shorter than binary for same data
Spaces are ignored in input for decoding
Invalid characters are automatically removed
Use for encoding/obfuscating text
