Detailed explanation-1: -Lempel Ziv algorithms are widely used in compression utilities such as gzip, GIF image compression and the V. 42 modem standard.

Detailed explanation-2: -Advantages of LZW over Huffman The algorithm is straightforward, simple, and effective. LZW does not require any prior knowledge of the input data stream. The LZW algorithm has a 60-70% compression ratio for some text files. The LZW algorithm performs better for files with a lot of repetitive data.

Detailed explanation-3: -The LZW method achieves compression by using codes 256 through 4095 to represent sequences of bytes. For example, code 523 may represent the sequence of three bytes: 231 124 234. Each time the compression algorithm encounters this sequence in the input file, code 523 is placed in the encoded file.
