Learn about the first compression of decompression. The Prophet reorganized the original file according to a certain coding method, which has many advantages, such as preventing the file from being destroyed, facilitating transmission, and setting a password to protect privacy. Decompression: It is the reverse operation of compression. Some people often use compression tools, and most of them think that compression is to make the original file smaller and easier to store. This is also an advantage, but, for example, pictures or some software-generated files, the compressed files are almost the same as the source files. Files such as video and audio can be compressed before releasing a lot of space. But it's best not to compress, because decompression is later, not 100% restore, so the quality can't be guaranteed, decompression errors will occur, or files will be damaged.
