Failure
Failure is any defect which occurs after the execution of the project.
Fault
Fault is any defect identified before execution or completion of the project.
Difference between Version, Variant and Release
Version
An instance of a system, which is functionality distinct in some way from other system instances.
Variant
An instance of a system, which is functionality identical but non-functionality distinct from other instances of a system.
Release

Difference between Wrong, Missing & Extra (Defect)
A defect is a variance from a desired product attribute, either from product specifications(producer view) or from customer/ user expectations(customer view).
Defects are of the following three categories:
Wrong
The defect is a variance from customer/ user specification when the specifications have been implemented incorrectly.
Missing
A specified or wanted requirement is not in the built product. This can be a variance from specification or the specification was not implemented.
Extra
A requirement incorporated into the product that was not specified. This is always a variance from specifications, but may the user of the product desire an attribute.
