The Internet Assigned Numbers Authority (IANA) maintains the official registry of HTTP status codes. [2] All HTTP response status codes are separated into five classes or categories. The first digit of the status code defines the class of response, while the last two digits do not have any classifying or categorization role.

The American mathematician Richard Hamming pioneered this field in the 1940s and invented the first error-correcting code in 1950: the Hamming (7,4) code. [5] FEC can be applied in situations where re-transmissions are costly or impossible, such as one-way communication links or when transmitting to multiple receivers in multicast.
Key Code Qualifier is an error-code returned by a SCSI device. When a SCSI target device returns a check condition in response to a command , the initiator usually then issues a SCSI Request Sense command .

p 1 covers d 1, d 2, d 4; p 2 covers d 1, d 3, d 4; p 3 covers d 2, d 3, d 4; The remaining rows (3, 5, 6, 7) map the data to their position in encoded form and there is only 1 in that row so it is an identical copy. In fact, these four rows are linearly independent and form the identity matrix (by design, not coincidence).
Since [7, 4, 3] = [n, k, d] = [2 m − 1, 2 m − 1 − m, 3]. The parity-check matrix H of a Hamming code is constructed by listing all columns of length m that are pair-wise independent. Thus H is a matrix whose left side is all of the nonzero n -tuples where order of the n -tuples in the columns of matrix does not matter.
Media Degradation: Over time, storage media like optical discs or magnetic tapes can degrade, leading to read/write errors. Physical Damage: Physical shocks, drops, or other mechanical damage to the storage device can result in Medium Errors.
