Hamming's Correction of Single Errors, continued

For example, ASCII character 'c' = 1100011, using even parity : 


         1  2  3  4  5  6  7  8  9 10 11
        ---------------------------------
               1     1  0  0     0  1  1


check 1        X     X     X     X     X

check 2        X        X  X        X  X

check 3              X  X  X

check 4                          X  X  X

The resulting codeword is hence 11111000011.

We then transmit this codeword across the network.
