An error is that part of the system state which is liable to lead to subsequent failure: an error affecting the service is an indication that a failure occurs or has Additional Information about Defects / Bugs: While testing a software application or product if large number of defects are found then it’s called Buggy. So developer introduce defects because of errors, tetsre find the failure and developer again find the defect by debugging i.e. Developer knows it is suppose to produce that result but ultimately it didn't.
