gzip is a file format and a software application used for file compression and decompression.The program was created by Jean-loup Gailly and Mark Adler as a free software replacement for the compress program used in early Unix systems, and intended for use by GNU (from which the "g" of gzip is derived).
libzip is an open-source library for handling zip archives. It is written in portable C and can thus be used on multiple operating systems. It is based on zlib. It is used by PHP's zip extension for zip file support [2] and MySQL Workbench. [3] It is also used by KDE's ark archiving tool for zip archive support.
mod_gzip is an external extension module for the Apache HTTP Server v1 and v2. It allows using the Gzip compression method for a significant reduction of the volume of web page content served over the HTTP protocol. mod_gzip can be compiled into Apache as either a static or dynamic module.
7-Zip is a free and open-source file archiver, a utility used to place groups of files within compressed containers known as "archives". It is developed by Igor Pavlov and was first released in 1999. It is developed by Igor Pavlov and was first released in 1999.
The mod_gzip module is similar to mod_deflate, for Apache v1 and v2. A mod_gz module was independently developed by Ian Holsman. This module implements a gzip compression filter for Apache 2.0, providing similar functionality to mod_gzip. One important difference between the two modules is that mod_gzip includes its own gzip implementation ...
The compression ratio is 20–100% lower than gzip. [5] Snappy is widely used in Google projects like Bigtable, MapReduce and in compressing data for Google's internal RPC systems. It can be used in open-source projects like MariaDB ColumnStore, [6] Cassandra, Couchbase, Hadoop, LevelDB, MongoDB, RocksDB, Lucene, Spark, InfluxDB, [7] and Ceph. [8]
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.It only compresses single files and is not a file archiver.It relies on separate external utilities such as tar for tasks such as handling multiple files, and other tools for encryption, and archive splitting.
In computing, Deflate (stylized as DEFLATE, and also called Flate [1] [2]) is a lossless data compression file format that uses a combination of LZ77 and Huffman coding.It was designed by Phil Katz, for version 2 of his PKZIP archiving tool.
