2. Bug tracking system
It is a software application that is designed for quality assurance and helps the programmers to keep track of reported software bugs in their work. It is a sort of issue tracking system.
The major component of bug
tracking system is a database that
records facts about known bugs.

3. Concurrent version system
It is an open source version
control system that keeps track
of all changes in a set of files,
typically the implementation
of a software project and it
allows several developers to
collaborate.
The major components in CVS is a repository which is master copy where CVS stores a full revision history.

4. Features of bug tracking system
The major component of bug tracking system is a database that records facts about known bugs.Facts may be the time of the bug, the nature of the bug, the behavior and details on what produced a bug.
Typical bug tracking system supports the concept of lifecycle for a bug which is tracked through status assigned to the bug.

5. Features of CVS. The key terms of CVS are: Repository:The master copy
where CVs stores the revision
History.
Working Copy:The copy in
which actual changes are made.
Typical CVS system supports
several programmers to work
concurrently.The server will accept
the changes made to the most
recent version of file.Developers
are therefore expected to keep
their working copy up to date by
incorporating other peoples changes.
The key terms in CVS are:
1.Check out: To get the working copy from repository.
2.commit:To send changes from working copy to repository.
3. Update: To bring about the changes made in the other working copies.
4. Conflict: When two programmers commit to some changes to the same region of the file.
5.Log Message:A comment to the revision history which we attach after committing.
6.Release: to logout of the Cvs server.

6. Limitations of CVS 1. CVS only shows what the conflicts are but does not give a procedure to solve it 2. Limited support for Unicode text file and non -ASCII filenames.
Examples:
Mantis and TRAC:Mantis is an example of web based bug tracking
system.It is written in PHP and requires a SQL database Server.It is a lightweight ,simple bug tracking system.
TRAC matches to mantis.

8. Conclusion
So the Bug tracking system and the Concurrent version system both enable the programmers to keep track of the bugs by using different mechanisms and there by enable the programmers to resolve the errors in a easy way
