The Hamming(7,4) code adds three parity bits to four data bits so any single-bit error can be found and fixed. Each parity bit checks a different overlapping group; after transmission, recomputing them gives a syndrome whose binary value points straight at the corrupted position. Error-correcting codes like this protect RAM, deep-space links, and QR codes.

Governing equation

d_{m i n} = 3, R = \frac{k}{n} = \frac{4}{7}, s = (000)_{2} = 0

Reading this result: No bit was flipped, so all three parity checks pass and the syndrome is 0 — the receiver accepts the codeword unchanged.

About this simulation

The full Hamming Code tool models a message digest with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
