Basic concepts:Compression: The file according to some algorithm to reduce, such as a text file content is: AAAAADDDD We can simplify it as a5d4 need to restore back, so that the original text storage needs 18 Bytes, now only need 8 bytes, greatly save space, generally speaking, the simpler the compression algorithm, The faster the compression speed, the more complex the algorithm, the higher the compression ratio [(the size before compression-the size after compression)/the size before compress
