Berkeley Software Distribution

Berkeley Software Distribution (BSD) is 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.

Command-line interface

A command-line interface or command language interpreter (CLI), also known as command-line user interface, console user interface, and character user interface (CUI), is a means of interacting with a computer program where the user (or client) issues commands to the program in the form of successive lines of text (command lines).

Data compression

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

Data compression ratio

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.

Filename extension

A filename extension is an identifier specified as a suffix to the name by syntax, often separated from the base filename (by, e.g., a dot, a space), that indicates, e.g., the encoding (file format), the usage, of a computer file.

The Graphics Interchange Format (better known by its acronym GIF or) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.

Image compression

The objective of image compression is to reduce irrelevance and redundancy of the image data in order to be able to store or transmit data in an efficient form.

Pipeline (Unix)

In Unix-like computer operating systems (and, to some extent, Microsoft Windows), a pipeline is a set of processes chained by their standard streams, so that the output of each process (stdout) feeds directly as input (stdin) to the next one.

Standard streams

In computer programming, standard streams are preconnected input and output communication channels between a computer program and its environment when it begins execution.
