WebJan 7, 1998 · Work in codes is related to packing problems and the error-correcting codes discovered by Hamming led to the solution of a packing problem for matrices over finite fields. In 1956 Hamming worked on the early computer, the IBM 650. His work here led to the development of a programming language which has evolved into the high-level … WebHow does Hamming Code work? The algorithm proposed by Richard Hamming takes a binary message (composed of bits 0 and 1) accompanied by a few additional bits encoding information on the number and position of 1 bits in the message.
