What is Huffman coding with example?

Huffman coding is a lossless data compression algorithm. In this algorithm, a variable-length code is assigned to input different characters. The code length is related to how frequently characters are used. Most frequent characters have the smallest codes and longer codes for least frequent characters.

Is Huffman coding lossy or lossless?

In computer science and information theory, a Huffman code is a particular type of optimal prefix code that is commonly used for lossless data compression.

How is Huffman coding used to compress data?

Huffman coding is a compression technique used to reduce the number of bits needed to send or store a message. Huffman coding is based on the frequency of occurrence of a data item (pixel in images). The principle is to use a lower number of bits to encode the data that occurs more frequently.
