lzma LZMA uses lossless data compression along with various algorithms. Been in development since 1996, it was originally used by the 7-zip software for computers like the 7z format. The algorithm uses a dictionary-like compression scheme that has similarities to the algorithm created by Jacob and Abraham Lempel in 1977, the LZ77 algorithm. The LZMA algorithm boasts an increased ratio of compression and a 4-gigabyte variable dictionary sized compression. The LZMA decompression speed is the same as other compression software algorithms.
jar A .jar extension file is a Java Archive format file that is used to store a large number of files into one single file. The basic advantages of .jar extension files are data compression, archiving, decompression, unpacking of the archived file and electronic signing which is one of the advanced features of this format. The Java Development Kit (JDK) contains the Java Archive Tool that is used to perform the basic tasks on .jar extension files. The JAR format is similar to a ZIP file format and it was specifically developed to help download Java applets and its components that include class files, images and sounds in one single HTTP transaction.
