A mistake in coding is called Error, error found by tester is called Defect, defect accepted by development team then it is called Bug, build does not meet the requirements then it Is Failure.

DEFECT: It can be simply defined as a variance between expected and actual. Defect is an error found AFTER the application goes into production. It commonly refers to several troubles with the software products, with its external behavior or with its internal features.

Failure: A failure is the inability of a software system or component to perform its required functions within specified performance requirements. When a defect reaches the end customer it is called a Failure. During development Failures are usually observed by testers.
