Thus, one can consider data compression as data differencing with empty source data, the compressed file corresponding to a "difference from nothing." This is the same as considering absolute entropy (corresponding to data compression) as a special case of relative entropy (corresponding to data differencing) with no initial data. Introduction to Data Compression “Methods for Data Compression”. The patent application clai med that if it was applied recursively, As we will see, this theory matches practice almost perfectly, and we can achieve code lengths almost identical to what the theory predicts. What data can be compressed? US Patent 5,, on "Methods for Data Compression", which is capable of compression all files. Slashdot reports of the Zero Space Tuner™ and BinaryAccelerator™. "ZeoSync has announced a breakthrough in data compression that allows for lossless compression of random data. If this is true. Data compressionimplies sending or storing a smaller number of bits. Although many methods are used for this purpose, in general these methods can be divided into two broad categories: lossless and lossy methods. Figure Data compression methods LOSSLESS COMPRESSION In lossless data compression, the integrity of the data is preserved.
