A failure occurs when the observed behaviour differs from the expected one. Note that the reference is the expected behaviour, not the specification, since even the spec could be false.
An error is the part of the system state which may lead to a failure.
A fault is the cause of an error. A software fault lies in software, a hardware fault lies in hardware.
According to the ISQTB a fault is a defect. There definition of a defect is as follows:
defect: A flaw in a component or system that can cause the component or system to fail to perform its required function, e.g. an incorrect statement or data definition. A defect, if encountered during execution, may cause a failure of the component or system.
failure: Deviation of the component or system from its expected delivery, service or result.
Basically, defects, bugs and errors are the same.
