A Comprehensive Review of Data Compression Techniques

In these days communication and storage of data becomes a huge challenge because of its large amount. Data which we store or transmit is generally redundant in direct or indirect form. Data compression is a process of reducing the size of data which is being stored or transmit by controlling redundancy in given data. Transmission or storage of large amount of data increase hardware and transmission cost. Hence selection of good data compression algorithm is very important. Data compression involves encoding information using fewer bits than the original representation. This paper presents the different data compression techniques and conclusion will be derived on the basis of these techniques.
