lossy
DATA COMPRESSION APPROACH THAT RESULTS IN LOSS OR CHANGE OF SOME DATA
Lossy; Lossy encoding; Lossy data compression; Data compression/lossy; List of lossy compression methods; Irreversible compression
<algorithm> A term describing a data compression algorithm
which actually reduces the amount of information in the data,
rather than just the number of bits used to represent that
information. The lost information is usually removed because
it is subjectively less important to the quality of the data
(usually an image or sound) or because it can be recovered
reasonably by interpolation from the remaining data.
MPEG and JPEG are examples of lossy compression
techniques.
Opposite: lossless.

A compression artifact (or artefact) is a noticeable distortion of media (including images, audio, and video) caused by the application of lossy compression. Lossy data compression involves discarding some of the media's data so that it becomes small enough to be stored within the desired disk space or transmitted (streamed) within the available bandwidth (known as the data rate or bit rate).

Lossy; Lossy encoding; Lossy data compression; Data compression/lossy; List of lossy compression methods; Irreversible compression
¦ adjective
1. having or involving dissipation of electrical or electromagnetic energy.
2. Computing (of data compression) in which unnecessary information is discarded.
Virtual memory compression
RAM Compression; Memory compression; RAM compression; Compressed RAM
Virtual memory compression (also referred to as RAM compression and memory compression) is a memory management technique that utilizes data compression to reduce the size or number of paging requests to and from the auxiliary storage. In a virtual memory compression system, pages to be paged out of virtual memory are compressed and stored in physical memory, which is usually random-access memory (RAM), or sent as compressed to auxiliary storage such as a hard disk drive (HDD) or solid-state drive (SSD).
Lossy compression
DATA COMPRESSION APPROACH THAT RESULTS IN LOSS OR CHANGE OF SOME DATA
Lossy; Lossy encoding; Lossy data compression; Data compression/lossy; List of lossy compression methods; Irreversible compression
In information technology, lossy compression or irreversible compression is the class of data compression methods that uses inexact approximations and partial data discarding to represent the content. These techniques are used to reduce data size for storing, handling, and transmitting content.

Data compression symmetry
Symmetry and asymmetry, in the context of data compression, refer to the time relation between compression and decompression for a given compression algorithm.
If an algorithm takes the same time to compress a data archive as it does to decompress it, it is considered symmetrical. Note that compression and decompression, even for a symmetric algorithm, may not be perfectly symmetric in practice, depending on the devices the data is being copied to and from, and other factors such as latency and the fragmentation on the device.
In turn, if the compression and decompression times of an algorithm are vastly different, it is considered asymmetrical.
