This paper focuses on the compression technique implemented by BZIP2 and its comparison to one of the existing compression techniques ?GZIP? and ?XZ?. This Paper also discusses the various algorithms used in BZIP2.The comparison between both the techniques include factors like Compressed file size upon comparison, compression time and decompression time. The techniques mentioned here are lossless.
