Bugs and Faults

Question

I am very confused with these two terms- Bugs and faults, I am not able to differentiate between both of them. Could anyone here help me out for this?

Fault & Mistake: wrong coding done by Developers Bug/Defect : A bug or defect is a flaw in a system or system component which may cause the system or the system component fail to perform its desired action.

Sam Hobbs · Answer

As Vulpes indicates, there is no formal definition. One possible distinction could be that a bug is the symptoms and a fault is the cause, but that is more of a guess than anything definitive.

Vulpes · Answer

I would say there's no difference between the terms 'bug' and 'fault' in software development - they both mean the same thing though 'bug' is less formal. My view is supported by Wikipedia which says: "A software bug is the common term used to describe an error, flaw, mistake, failure, or fault in a computer program or system that produces an incorrect or unexpected result, or causes it to behave in unintended ways." http://en.wikipedia.org/wiki/Software_bug

Hi Laura, Normal 0 Error: A discrepancy between a computed, observed, or measured value or condition and the true, specified, or theoretically correct value or condition. Failure: The inability of a system or component to perform its required functions within specified performance requirements. Bug: A fault in a program, which causes the program to perform in an unintended or unanticipated manner. Fault: An incorrect step, process, or data definition in a computer program, which causes the program to perform in an unintended or unanticipated manner. Defect: Mismatch between the requirements. Thanks
