Thanks. Satisfactory answer.
This question do confuses a lot. There is a slight difference between these terms but most of the people think that they are same. But you have made it clear that they are different.
Software testing videos
good answer,
explain with proper example.

So... if there is a fault in the system code but the user never perceives it, is it really a bug?
Mmm, programming Zen...
Thank you. Excellent Post.
best ans.
thank you very much
actually error is caused by human mistakes
V good information
very good & clear answer.
thanks
thanks for ur clear definition.
I Got very good answer
very useful ya
thanks! informative !
Bug example:
1. crash while click on any button.
2. Deadlock, unable to move on next page.
Defects:
1. Wrong calculations.
2. Unexpected result.
3. Result not as per the requirement.etc
error is caused by human mistakes.
Bug is variance between actual n expected result.
really goooood work..thanx a lot...
I think its the best answer as I have searched many sites for it.....thanx again...
for this answer please visit once at www.testingdream.com
it will help you...
thanks for letting me know some of the basic terminologies relate to computer
Thanks for valid information.......If there is no error in program than no bug,no failure will become..
Good explanation.
Thanks.
Error:Progamatically mistake leads to error.
Bug:Deviation from the expected result.
Defect:Problem in algorithm lead to failure
Failure:When everything is correct but we are not able to get a result
Ya Realy its helpful for us who are preparing for the interview and to learn things...Thanks
Good 1 :D
Nice Answer
Difference between Testing and Debugging
Error: An Human actions produce some incorrect results that is called error.
Bug:During the execution of program founding some error.
Defect:- What we supposed to do and does not work as what we excepted in the behavior of application.
Failure:When software is relesed, the customers found some defects or application may be crash by using any wrong functionality that is called software Failure.
I hope you all like this answer.

Have gone through multiple websites before stumbling upon this one.. perfect answer! kudos!
Thnx alot for the clear definition..it help me alot to understand the basic differences betwen these terms..
Thanks
fault : problem that can be rewinded to overcome the loss
failure :problem that results in certain assets loss..
Welcome...
Defects: The concrete manifestations of errors within the software. One error may cause several defects and various errors may cause identical defects
Error: Finding defects without executing of any code through verification of document.
