Block Codes

Block codes are error-correcting codes in which a block of input data is transformed into a block of output data using an algorithm. The output data is then transmitted over a noisy channel, and the receiver can detect and correct any errors that may have occurred during transmission, based on the block code used. This property of block codes makes them highly desirable in communication, as they enable secure transmission of data with minimal errors. Block codes are also used in data storage, where they can detect and correct errors due to physical defects in storage media.
