The different types of compression

There are two main types of compression:

.Lossy- techniques in which some amount of data is lost. Lossy compression technologies attempt to eliminate redundant or unnecessary information. Most video compression technologies, such as MPEG, use a lossy technique.

Lossless- This one is very smart as it try's to retain everything. Its is also possible to compress a file and lose any data.
