Vol. 3 No. 4 (2011): Data compression is widely required

Data compression is widely required in the era Information-communication where it can be used to conserve the energy of networks, because a file with reduced size requires less time to get passed over the Thus the technique of compression and decompression can be quite effective in establishing efficient communication over the computer networks. The work performed in the paper, compares the Loss less data compression algorithms and analyses various compression ratio, compression speed, decompression speed, saving percentage. An experimental comparison of a number of different lossless data compression algorithms is presented in this paper. The article is concluded by stating which algorithm performs well for text data.
