Bharath 02 08 This paper presents a review kind of data compression ways Data compression is extensively used by the community because through a compression we can save storehouse Data compression can also speed up a transmission of data from one person to another In performing a compression requires a system of data compression that can be used the system can also be used to compress a data Data that can be compressed not only textbook data but can be images and videotape Data compression fashion is divided into 2 videlicet lossy compression and lossless compression But which is frequently used to perform a compression thats lossless compression A kind of lossless condensing similar as Huffman Shannon Fano Tunstall Lempel Ziv welch and run length encoding Each system has the capability to perform a different compression This paper explains how a system works in doing a compression and explains which system is well used in doing a data compression in the form of textbook The affair generated in doing a can be known through the compression train size that becomes lower than the original train Copyright (c) Journal of Science Engineering Technology and Management Science.
