Error : Is an undesirable deviation from requirements
Bug : Is an error found BEFORE the application goes into production
Defect :Is an error found AFTER the application goes into production
Any deviation from requirement is a bug , which may or may not cause failure. But defect is the one which wil cause the software failure. I mean a software can run without failure with bugs in it. But a software cant run withour failure with defects in it.
Bug is any inconsistance with requirement, where defect scope is higher than bug, its the inconssitancies of requirement associating with severity, priority, root cause, to the specifice bug, it's reffered as defect.
AFAIK, The description for the term Defect is not as u said.
ERROR = A mistake found during the development/coding of the application.
ISSUE = In the application is any deviation/Mismatch we observed otherthan the Expected Result.
DEFECT = An issue logged in Quality Centre.
BUG = The Defect accepted by the development called BUG.
FAILURE = This is the term i heard many times if there is any mismatch in Production (after the app's goes to prod.)
Many people have their own kinds of definitions on this terms. I never heard an error error occured in production is called as Defect. Totaly its a failure of that app's.

Defect: The Codes are developed and still the expected results are not obtained due to the non conformance of requirements then it is called defect
Kindly correct me If I am wrong
