Base-16 system using digits 0–9 and A–F. Each hex digit represents exactly 4 bits (a nibble). Widely used in computing for memory addresses, colors (#FF5733), and binary data.
Base-2 system using only 0 and 1. This is the native language of all digital computers. Every byte is 8 bits (00000000 to 11111111), representing values 0 to 255.
Each hex digit maps directly to a 4-bit binary group. F = 1111, A = 1010, 0 = 0000. So 0xFA = 1111 1010. This direct mapping makes hex a convenient shorthand for binary.
HTML colors (#RRGGBB), IPv6 addresses, SHA/MD5 hashes, Unicode code points (U+1F600), machine code, network packets — all commonly represented in hexadecimal.
