Difference B/w Error, Bugs, Defect, Fault & Failure

Error: Errors are basically the deviation from the requirement, caught by testers and caused by misunderstanding of the Developers.

Bug: If the Error found by testers are accepted as error by Developers. Then the error will called Bug.

Defect: Suppose any product/software is currently running as a beta version in the market/client side. Any issue currently caught in that application that are deviating the actual result from the requirement, will taken as Defect.

Fault: When the product/software successfully launched in the market and running properly but due to any reason if it works unexpectedly is called Fault.

Failure: If the product fails to full fill the requirement, then it is called Failure.
