- 1Lossy Compression Definitionlossy compression is a type of compression where a certain amount of information is discarded. As an aside, the time may soon come when storage is so cheap that there is no need for lossy compression. lossy compression, on the other hand, means some data are lost during shrinking.
- 2Lossy Compression ExplanationRefers to data compression techniques in which some amount of data is lost. Lossy compression technologies attempt to eliminate redundant or unnecessary information.

MP3 - 4Lossless Compression DefinitionLossless data compression is a class of data compression algorithms that allows the original data to be perfectly reconstructed from the compressed data.
- 5Lossless Compression explanationFor most types of data, lossless compression techniques can reduce the space needed by only about 50%. For greater compression, one must use a lossy compression technique. Note, however, that only certain types of data -- graphics, audio, and video -- can tolerate lossy compression. You must use a lossless compression technique when compressing data and programs.
