Research of Several Common Lossless Data Compression Algorithms

With the quick increase of network's information,data compression is paid more and more attention by people.Data compression can be divided into two types,one is called lossless compression,and the other is called loss compression.It takes lossless data compression as main line.According to different compression technology of lossless data compression,from two aspects of statistic and dictionary ideas,it introduces some representative lossless data compression approaches and analyzes these kinds of data compression algorithms' advantages and disadvantages.Gather some mature betterment algorithm based on dictionary compression algorithm together and introduce them;It is facilitate reference for people who is interest in lossless data compression technology.
