4) Failure :- A defect which is missed by the test team, which is later detected in Production environment by end user (Customer/Client) is called a failure. This is often a major escalation on the part of the tester, since he/she was not able to catch the issue before it went to production.

Defect: Any human made mistakes

Error: Any mistakes done at code level failure. If the overall software development deviates from the requirements its called as failure.

These are inter-dependent.

Error: You provide the wrong information and do now receive the expected result, it is an error.

Failure: If the resulting output does not meet the requirements then it is a failure.

Defect: Even after giving the right information you are not able to get through the page, then it is a defect.
