2. Lempel–Ziv–Markov chain algorithm - Wikipedia

   en.wikipedia.org/wiki/Lempel–Ziv–Markov_chain...

   The Lempel–Ziv–Markov chain algorithm (LZMA) is an algorithm used to perform lossless data compression. It has been under development since either 1996 or 1998 by Igor Pavlov [1] and was first used in the 7z format of the 7-Zip archiver. This algorithm uses a dictionary compression scheme somewhat similar to the LZ77 algorithm published by ...

3. Lossless compression - Wikipedia

   en.wikipedia.org/wiki/Lossless_compression

   Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only of an approximation of ...

4. Lempel–Ziv–Oberhumer - Wikipedia

   en.wikipedia.org/wiki/Lempel–Ziv–Oberhumer

   The original "lzop" implementation, released in 1996, was developed by Markus Franz Xaver Johannes Oberhumer, based on earlier algorithms by Abraham Lempel and Jacob Ziv. The LZO library implements a number of algorithms with the following characteristics: Higher compression speed compared to DEFLATE compression. Very fast decompression.

5. LZ77 and LZ78 - Wikipedia

   en.wikipedia.org/wiki/LZ77_and_LZ78

   LZ77 and LZ78 are the two lossless data compression algorithms published in papers by Abraham Lempel and Jacob Ziv in 1977 [1] and 1978. [2] They are also known as LZ1 and LZ2 respectively. [3] These two algorithms form the basis for many variations including LZW, LZSS, LZMA and others. Besides their academic influence, these algorithms formed ...

   Unix-like. RPM files consist of metadata concatenated with (usually) a cpio archive. Newer RPM systems also support other archives, as cpio is becoming obsolete. cpio is also used with initramfs. .shar. application/x-shar. Shell archive. Unix-like. A self-extracting archive that uses the Bourne shell (sh). .LBR.
