lz - Computer Definition
A compression algorithm used in some modems, LZ achieves compression ratios of better than 5:1 for some forms of text and numerical data. LZ compression allows the data terminal equipment (DTE) to operate at speeds up to 128 kbps while the analog link between the modems remains at 38.4 kbps or less over a 4 kHz channel. LZ is named after its inventors, Abraham Lempel and Jacob Ziv. See also analog, channel, compression, DTE, link, modem, and LZW.
