Number Base Systems

Computers operate in binary (base 2), but programmers frequently work with decimal (base 10), octal (base 8), and hexadecimal (base 16). Understanding these systems is essential for low-level programming, networking, and color codes.

Quick Reference

• 0xFF = 255 in decimal = 11111111 in binary
• 0x0A = 10 in decimal = 1010 in binary
• An IPv4 octet ranges from 0-255 (0x00-0xFF)
• A byte has 8 bits and ranges from 00000000 to 11111111
