During the advanced era of modern science data has become a salient part of research as well as other methodologies. Along with the cumulative use of data, data redundancy has become an ache for both user and researcher end. Not only communication but also generic file compression technologies are using different kind of efficient data compression methods massively day by day. This paper concerns with a variety of data compression methods with some efficient innovation. The purpose of data compression is to wan redundancy in stored or communicated data. Data compression has important application in the area of file storage and distributed system. This paper will provide an overture of several compression methods and will formulate new methods that may improve compression ratio and lessen error in the reconstructed data. In this work the data compression techniques: Huffman, Run-Length, LZW, LZW-Huffman, Huffman-LZW, Run-Length-LZW and LZW-Run-Length are used to compress different types of multimedia formats such as images and text, which depicts the discrepancy of various data compression methods on image and text file.
