A method of reducing the size of files or programs so that they can be downloaded or distributed more easily.
(Learning Modules / Mathematics / Bridges) Any force that acts in order to shorten, or push together the ends of, a structural element. When pushing your hands together, your arms will be under compression. The towers of a suspension bridge, and the piers of an arch bridge, are under compression.
Compression expresses the given picture will less data and compression rate alone does not give an indication of final picture quality. It is necessary to compress the data in order to store and transmit digital television data using an economical amount of bandwidth. Different rates of compression are used with different and practically, the more data used the better the image quality. Multiple generations of compressed images always result in image degradation.
using an algorithm to decrease the number of bits of user data to be transmitted, thereby increasing the efficiency of a communications channel. A related algorithm will expand the data back to its original form when it is received. In data communications compression is usually lossless, the original data is restored exactly as sent. For analogue services like speech (see codec) and pictures (see pixels), compression with some loss is often acceptable and a mobile phone codec will exploit this to achieve very high compression factors.
Type: Term Pronunciation: kom-presh′ŭn Definitions: 1. A squeezing together; the exertion of pressure on a body in such a way as to tend to increase its density; the decrease in a dimension of a body under the action of two external forces directed toward one another in the same straight line.Found on http://www.medilexicon.com/medicaldictionary.php?t=19553

A technique to reduce the size of a file in order to make it more manageable and quicker to download. Compressed files have to be extracted using a utility such as PKZip or WinZip. Such files usually have a .zip extension.Found on http://www.mantex.co.uk/samples/glo-1.htm

A process that uses an algorithm to reduce data volume while preserving the original data content. Compression is used to reduce the time required to send and receive data over a network, and to enable the recording of more data onto a memory card or other storage medium.

Means of reducing stored image file sizes. Commonly used in DIP systems where the bit-map image for an A4 page is typically reduced to around 40KByte, but also used for program and data files in order to increase disk capacity. Decompression is the process which restores files to their original state.

(Digital cameras and photo printers) Data may be compressed to reduce storage (memory) space or transmission times (= reducing the amount of data). Well-known compression standards include JPEG and MPEG.Found on http://www.encyclo.co.uk/local/20472
many image files, both still and movie, can be greatly reduced in size using compression. Lossless compression gets rid of redundancy but leaves the image pristine. Lossy compression reduces the size of images by throwing away information that the eye should not miss. Done badly, lossy compression can cause visible artefacts

The raw 'bit image' delivered by a scanner to a computer is extremely large and wasteful of storage and transmission capacity. Coding algorithms and systems have been devised to compress the image, e.g. by making use of the fact that most documents have many 'white' or single tone areas. Decompression must take place before viewing or printing - ad...Found on http://www.isomatic.co.uk/WBGlossary.htm

The main way that digital can offer more channels is by compressing the signal. A lame example, but say you have a row of pixels that are all blue... You can either say: a blue pixel, a blue pixel, a blue pixel, a blue pixel, a blue pixel (etc...635 times more!) which is wasteful (and how analogue works), or you can say: a blue pixel - repeat six h...Found on http://www.heyrick.co.uk/ricksworld/digibox/glossary.html
A technique for reducing the quantity of data required to make up a digital image. Compression techniques can be non-destructive (â€˜lossless`) or destructive (â€˜lossy`), in which part of the data set is discarded permanently. Converting still images into JPEG format is one example of lossy compression.

The act of pressing together. It can result in deformation (as in shortening a spring) and improvement in, or creation of, stability. Compression is used (1) to provide absolute stability of fracture fixation, where indicated, and (2) to protect the fixation implants and to improve their efficiency by reducing the dynamic stresses on them them.

Broadly in two forms - 'lossy' and 'losless'. JPEG is a lossy compression format; it discards information on a sliding scale of size v. quality. With size over quality the image pixelates. Each time it is compressed it throws away more data.

Compression: 1. The act of pressing together. As in a compression fracture, nerve compression, or spinal cord compression. 2. To shorten in time.

Many projectors are able to display higher resolutions than they actually have by skipping lines and columns. As this affects the picture quality, several manufacturers have developed special compression methods, which actually compress with only the slightest loss of information.Found on http://www.medium.co.uk/public/sales/glossaryc.html
