Flashcards: Data compression

Lempel–Ziv–Oberhumer (LZO) is a lossless data compression algorithm that is focused on decompression speed.

UPX (Ultimate Packer for Executables) is a free and open source executable packer supporting a number of file formats from different operating systems.

xz is a lossless data compression program and file format which incorporates the LZMA/LZMA2 compression algorithms.

Lossless compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.

In information technology, lossy compression or irreversible compression is the class of data encoding methods that uses inexact approximations and partial data discarding to represent the content.

zlib is a software library used for data compression.

bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.

gzip is a file format and a software application used for file compression and decompression.

WinZip is a shareware file archiver and compressor for Windows, OS X, iOS and Android developed by WinZip Computing (formerly Nico Mak Computing).

lzop is a free software file compression tool which implements the LZO algorithm and is licensed under the GPL.

Wandera is a privately held company backed by Bessemer Venture Partners and 83North Venture Capital.

Ocarina Networks was a technology company selling a hardware/software solution designed to reduce data footprints with file-aware storage optimization.
