Checking and Detection Of Errors
Hamming Code can self-correct single errors, which makes it a more reliable way of Finding and Correcting Errors.
Hamming Code involves using more than one parity bit in each bit pattern. The more data bits that are encoded,
more parity bits will be required to check the data. Even parity is used.
Error detection is good, error correction is better. How can we increase the chances that the data reaches its destination correctly? One method is to send each bit three times and use the idea of a majority vote to determine the correct bit. This is a very expensive method as three times the volume of data is transmitted.
even parity is where there is a even number of 1′s in the binary.
odd parity is where there is a odd number of 1′s in the binary.
