Mercurial is a distributed revision control (DRC) management system. Decentralization is one of its advantages. For an individual developer DRC systems are faster than centralized: all metadata is stored locally and you do not need to contact the central server each time you modified the code. Mercurial repository is self-contained. It means that all changes you have made will exist only in your local repository until you decide to propagate these changes to the remote one.
