WebHuffman Code. A Huffman code is a “type of optimal prefix code that is commonly used for lossless data compression”. There are three parts of that definition we have to unpack: … WebUnlike the ASCII code which uses exactly eight bits to encode each character, a Huffman code uses a variable number of bits for each character. With Huffman’s scheme, a common character such as “a” or “e” might be encoded with perhaps just two bits and less frequently used characters like “q” or “#” would be encoded with a longer bit string.
