Compression algorithm mainly has two kinds: one kind is reversible, that is, from compressed data can be fully recovering the original data, without any information loss, called lossless compression; Another type of compression is irreversible, that is and from compressed data can't fully recover the original data, information has a certain loss, called the lossy compression.
