LZW Data Compression Lempel”Ziv”Welch (LZW) is a lossless data compression technique that was created back in 1984 by Terry Welsh as an improvement to the popular LZ77 compression algorithm. LZW is ...

A lossless compression algorithm based on the LZW with compression ratios of 50 ? 60%, using 2K of RAM and 80% or more with 8K or 16K.

The first three are simple encoding techniques, called: run-length, Huffman, and delta encoding. The last two are elaborate procedures that have established themselves as industry standards: LZW and ...

Compression techniques that work well for one kind of data, such as the LZW compression algorithms used by WinZIP and PKzip for PC data files, are not necessarily effective on other kinds of data, ...
