A compressed file which is a TAR archive. Created for use in Unix systems. The TAR container combines several files into one archive that is placed in a TGZ compressed file. They’re used as installation packets in the installers of some operating systems.
A common format for compressing data. It’s used by a large number of applications for the exchange of data, back-ups and file compression. In ZIP archives they use various compression algorithms. The cryptographic algorithm is proprietary, so confidential data is better stored in an archive with a more complex protection system (RAR, 7z, etc.).
