Huffman coding is one of the most efficient and widely used algorithms for lossless data compression. Developed by David A. Huffman in 1952 while he was a Ph.D. student at MIT, this algorithm remains a cornerstone in information theory and digital communication. It forms the basis for many modern compression formats, including ZIP, JPEG, and MP3. The fundamental idea behind Huffman coding is simple yet powerful: assign shorter binary codes to more frequent symbols and longer codes to less frequent symbols, thereby reducing the total number of bits required to represent a dataset.
