Berkeley Software Distribution (BSD) was a Unix operating system derivative developed and distributed by the Computer Systems Research Group (CSRG) of the University of California, Berkeley, from 1977 to 1995.
bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm.
In signal processing, data compression, source coding, or bit-rate reduction involves encoding information using fewer bits than the original representation.
Data compression ratio, also known as compression power, is a computer science term used to quantify the reduction in data-representation size produced by a data compression algorithm.
In computing, Deflate is a lossless data compression algorithm and associated file format that uses a combination of the LZ77 algorithm and Huffman coding.
A filename extension is an identifier specified as a suffix to the name of a computer file.
The Graphics Interchange Format, better known by its acronym GIF, is a bitmap image format that was developed by a team at the bulletin board service (BBS) provider CompuServe led by American computer scientist Steve Wilhite on June 15, 1987.
gzip is a file format and a software application used for file compression and decompression.
Image compression is a type of data compression applied to digital images, to reduce their cost for storage or transmission.
Lempel–Ziv–Welch (LZW) is a universal lossless data compression algorithm created by Abraham Lempel, Jacob Ziv, and Terry Welch.
Linux is a family of free and open-source software operating systems built around the Linux kernel.
This is a list of Unix commands as specified by IEEE Std 1003.1-2008, which is part of the Single UNIX Specification (SUS).
Pack is a (now deprecated) Unix shell compression program based on Huffman coding.
In Unix-like computer operating systems, a pipeline is a sequence of processes chained together by their standard streams, so that the output of each process (stdout) feeds directly as input (stdin) to the next one.
The Portable Operating System Interface (POSIX) is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.
The Single UNIX Specification (SUS) is the collective name of a family of standards for computer operating systems, compliance with which is required to qualify for using the "UNIX" trademark.
In computer programming, standard streams are preconnected input and output communication channels between a computer program and its environment when it begins execution.
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.
Terry Archer Welch was an American computer scientist.
The University of Utah (also referred to as the U, U of U, or Utah) is a public coeducational space-grant research university in Salt Lake City, Utah, United States.
Unix (trademarked as UNIX) is a family of multitasking, multiuser computer operating systems that derive from the original AT&T Unix, development starting in the 1970s at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
A Unix shell is a command-line interpreter or shell that provides a traditional Unix-like command line user interface.
Usenet is a worldwide distributed discussion system available on computers.
