Hamming codes

Hamming codes are a method used in computer communication and storage to detect and correct errors in data transmission. They work by adding extra bits, called parity bits, to the original data, arranged in a way that allows the system to identify precisely where an error might have occurred. When the data is received, the system checks these parity bits to see if everything matches. If there's a mismatch, it can often pinpoint and fix single-bit errors automatically, ensuring the data remains accurate without needing to resend everything. This enhances reliability in digital communications.
