Understanding Number Systems

Computers use binary (base-2) internally—only 0 and 1 represent electrical states. Hexadecimal (base-16) is shorthand for binary: each hex digit represents 4 binary digits. Decimal (base-10) is human-friendly. Example: 255 decimal = 0xFF hex = 11111111 binary.

Binary to hex conversion: Group binary digits in sets of 4 from right to left. Each group becomes one hex digit. 1010 1100 = AC. Hex to decimal: (A × 16^1) + (C × 16^0) = (10 × 16) + (12 × 1) = 172. Text to binary: Each character's ASCII code converted to binary.

Use cases: Understanding memory addresses, debugging low-level code, analyzing network packets, working with color codes (CSS hex colors), understanding file formats, IP address subnet calculations, and learning computer science fundamentals.
