1 compression in general, the computer processing of data exist some redundancy, at the same time, the data, especially the correlation between adjacent data, so you can through some different from the original encoding of the special encoding method to save data, so that the data occupy a small amount of storage space, this process is generally called compression. The concept of compression corresponds to decompression, the process of restoring compressed data from a special encoding to the original data. Compression is widely used in mass data processing, compression of data files, can effectively reduce the space required to store files, and speed up data on the network or to ...

The file name extension for RAR is. Rar,mime type is application/x-rar-compressed. Similarly lossless data compression, RAR files are usually higher than zip file compression, but the compression speed is slower. Because the RAR file header also occupy a certain space, in the data compression is not large, compressed files may be larger than the original file. 　　 A main advantage of RAR is the file compression target can be divided into multiple files, and it is easy to extract from such a compressed file source files. In addition, RAR ...
