Whois & Analysis for jzip.com

7-Zip is an open-source file archiver, an application used primarily to compress files.

7-Zip uses its own 7z archive format, but can read and write several other archive formats.

The program can be used from a command-line interface as the command p7zip, as a graphical user interface, or with a window-based shell integration.

7-Zip began in 1999 and is developed by Igor Pavlov.

7-Zip is open-source software.

Most of the source code is under the GNU LGPL license.

The unRAR code is under the GNU LGPL with an "unRAR restriction", which states that developers are not permitted to use the code to reverse-engineer the RAR compression algorithm.

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 (the "g" is from "GNU").

Version 0.1 was first publicly released on 31 October 1992, and version 1.0 followed in February 1993.

RAR is a proprietary archive file format that supports data compression, error recovery and file spanning.

It was developed by a Russian software engineer, Eugene Roshal (the name RAR stands for Roshal Archive) and the RAR software is licensed by win.rar GmbH.

In computing, tar is a computer software utility for collecting many files into one archive file, often referred to as a tarball, for distribution or backup purposes.

The name is derived from (t)ape (ar)chive, as it was originally developed to write data to sequential I/O devices with no file system of their own.

The archive data sets created by tar contain various file system parameters, such as name, time stamps, ownership, file access permissions, and directory organization.

The command line utility was first introduced in the seventh edition of unix (v7) in January 1979, replacing the tp program.

The file structure to store this information was later standardized in POSIX.1-1988 and later POSIX.1-2001.

and became a format supported by most modern file archiving systems.

In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation.

Compression can be either lossy or lossless.

Lossless compression reduces bits by identifying and eliminating statistical redundancy.

No information is lost in lossless compression.

Lossy compression reduces bits by removing unnecessary or less important information.
