Defect,bug & failure

There is so much confusion among the new testers about the meaning of words defect,bug & failure.Here I just want to clear it.

• Defect’ is a deviation from actual behavior identified during the system testing phase.
• It becomes a bug, when development accepts the ‘defect’ raised by test and identifies the mistake in code.
• If a deviation occurs at the production environment or user end it is called as ‘failure’.

I hope this will clear your doubts.
