Version control tools are like Endevor, Changeman, OWL (used at the time of legacy) etc... We will save our modules using them. If any changes are made in our modules, updated module can be saved into them by incrementing the version. In this way we can keep track of all versions.
Retrieving the versions depends from tool to tool.
