Answer / paddu

Version control (also known as Revision control, source
control) is the management of multiple revisions of the
same unit of information usually the software. As software
is designed, developed and deployed, it is extremely common
for multiple versions of the same software to be deployed
in different sites, and for the software's developers to be
working simultaneously on updates. Bugs and other issues
with software are often only present in certain versions
(because of the fixing of some problems and the
introduction of others as the program develops). Therefore,
for the purposes of locating and fixing bugs, it is vitally
important to be able to retrieve and run different versions
of the software to determine in which version(s) the
problem occurs. It may also be necessary to develop two
versions of the software concurrently (for instance, where
one version has bugs fixed, but no new features, while the
other version is where new features are worked on). At the
simplest level, developers could simply retain multiple
copies of the different versions of the program, and number
them appropriately. This simple approach has been used on
many large software projects. While this method can work,
it is inefficient as many near-identical copies of the
program have to be maintained. This requires a lot of self-
discipline on the part of developers, and often leads to
mistakes. Consequently, systems to automate some or all of
the revision control process have been developed.
