    Accepted Solution

    You can read about continuous integration in Wikipedia:

    In particular they explain where such tools as Hudson or others ebecome useful in this process.
    Seems pretty understandable:

    Continuous integration – as the practice of frequently integrating one's new or changed code with the existing code repository – should occur frequently enough that no intervening window remains between commit and build, and such that no errors can arise without developers noticing them and correcting them immediately.[4] Normal practice is to trigger these builds by every commit to a repository, rather than a periodically scheduled build. The practicalities of doing this in a multi-developer environment of rapid commits are such that it's usual to trigger a short timer after each commit, then to start a build when either this timer expires, or after a rather longer interval since the last build. Automated tools such as CruiseControl or Jenkins or Hudson offer this scheduling automatically.

    Assisted Solution

    Its used to automate the build process such that when a code change is submitted the project gets automatically rebuilt and all tests are run.
    The advantage of this is that problem are identified immediately. These problems could be that the code does not compile or a test starts failing.  You can also stop any further code changes once a build is broken, forcing the developers to first fix the problem with the build.
