Defect : From Producer Point of View , Any Requirement that
is Missed out from that it was agreed to incorporate into
product . This can be found during Verification , means
Reviews and not in validation like Testing ..
eg. I design a car as per the need of Middle Segment and i
don't miss out what ever i have planned out ..
From Consumer Point of view , Anything that causes
dissatisfacti0on ,irrespective of Requiremnts were fully
incorporated or not ...
My customer finds that there in no Antilock system ..From
my point , I have produced a DEFECT - fREE Product ,but it
is still defective from customer point
Bug : When an unexpected thing happens from what is
Expected , it is Bug .It happens in Testing and in all
validation techniques..
While testing the car , the car has to withstand 100 N,but
it withstands only 80 N Force ..Its a bug !

Simply any thing find by tester its defect, when the
developer accepts the defect its bug. Any thing found
faulty ie fault is an error.
Fault--> Error--> Defect--> Bug
Pls correct me if it not correct.

Answer / satya
The Error is the wrong in the code, which causes runtime
errors or Page can not display errors or any syntax errors.
The Defect is the improper behaviour of the system or the
application, like if the button (Submit or Save) is not
working.
Bug is if the system doesnot meet the client requirement.
