Hammingkóða

Hammingkóða is a type of error-detecting and error-correcting code that was developed by Richard Hamming in 1950. It is a linear error-correcting code, which means it can detect and correct errors in data transmission. The Hamming code is particularly useful in digital communications and data storage systems where data integrity is crucial.

The Hamming code works by adding redundant parity bits to the original data. These parity bits are calculated based on specific positions in the data, allowing the code to detect and correct single-bit errors. The number of parity bits required is determined by the length of the data. For example, if the data is n bits long, the Hamming code will require k parity bits, where 2^k >= n + k + 1.

The Hamming code is efficient and straightforward to implement, making it a popular choice for error correction in various applications. It is widely used in computer memory, data transmission systems, and other areas where data integrity is essential. Despite its simplicity, the Hamming code is highly effective in detecting and correcting errors, making it a valuable tool in the field of digital communications.
