Hamming (7,4) Code

The Hamming (7,4) code is an error-correcting method that helps detect and fix mistakes in data transmission. It takes 4 data bits and adds 3 extra bits, called parity bits, which check for errors. When the data is sent, if any bit gets altered, the receiver can identify and correct the single-bit error using the parity information. This process ensures reliable communication, especially over noisy channels, by maintaining data integrity without needing to resend the entire message.
