![]() ![]() Hamming code can correct single-bit errors and detect the presence of two-bit errors in a data block. The data is divided into blocks, and parity is added to the block. Hamming code uses a block parity mechanism. FEC can increase the data transmission rate for noisy channels by reducing the amount of necessary retransmits. If enough parity data is added, it enables forward error correction (FEC), where errors can be automatically fixed when read back. This is done by adding parity bits, or redundant information, to the data. Error correcting codes seek to find when an error is introduced into some data. This can take the form of bit flips, where a binary 1 becomes a 0 or vice versa. Whenever data is transmitted or stored, it's possible that the data may become corrupted. It's named after its inventor, Richard W. It is commonly used in error correction code (ECC) RAM. It requires adding additional parity bits with the data. Hamming code is an error correction system that can detect and correct errors when data is stored or transmitted. ![]()
