Answer / garima
Error : A discrepancy between a computed, observed, or
measured value or condition and the true, specified, or
theoretically correct value or condition. See: anomaly,
bug, defect, exception, and fault
Failure: The inability of a system or component to perform
its required functions within specified performance
requirements. See: bug, crash, exception, fault.
Bug: A fault in a program which causes the program to
perform in an unintended or unanticipated manner. See:
anomaly, defect, error, exception, fault.
Fault: An incorrect step, process, or data definition in a
computer program which causes the program to perform in an
unintended or unanticipated manner. See: bug, defect,
error, exception.

Answer / veena nair
If we're talking about a problem that exists in the design
of DNS or
in a particular implementation, we should call it
a "defect" (this is
the standard term among the safety engineers for what we
programmers
informally call a "bug"). If we're talking about a problem
that
exists at run-time, when something goes wrong internally,
we should
call it a "fault". If we're talking about somebody getting
ripped off
because they relied on DNS and a criminal exploited DNS,
then we
should call it a "failure".

Answer / ravi
error:- a human action that give incorrect results
failure:-A Failure is a ‘Deviation of the component or
system from its expected delivery, service or result’
Failures can be caused by environmental conditions as well
E.g. radiation, magnetism, electronic fields
Pollution can cause faults in firmware or influence the
execution of software by changing hardware conditions.
defect:A flaw in a component or system that can cause the
component or system to fail to perform its required function
Bug:A mistake in coding called 'error'.If that error
identified by test engineer called defect. That defect is
fixed by developer is called bug.

Answer / msm.fathih
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.

Answer / anamika
Error means any deviations in the applications from the
requirements.
Bug means if the errors are identified during testing time.
defects means if the errors are not identified during
testing time,but are identified during production time.

Answer / gopaldas
1>Error or mistake is nothing but a human action which
produces an incorrect result.
2>Defect is a fault in the software due to human action
also called as Fault or Bug.
3>Failure is a deviation from expected behaviour.
