Hai friendz i am rajendra,
I would like to give simple and easy answer for this
question,
Error -A Fault in the program leads to error in program
exection.
Defect-If the error caught by tester then it is called
as defect.
Bug - If the defect is accepted by the development people
then it is called as Bug.
Fault---->Error---->Defect---->Bug
Error may be generated due to syntax or symantic fault.
Different types of error are
1.syntax errors
2.symantic errors
3.Logical errors
4.Runtime errors...etc
All athe above errors will be occured during white box
testing of the application/product.
In BlackBox testing main defects are
Requirement missing or
Wrongly interpreted requiremets,
Misoperation of fuctionalities...etc.
ok byeeee

Error: it is deviation from logic,syntax or execution.
there r 3 types of errors
syntactical error: it is deviation from syntax of program
logical error: it is deviation from logic of the program.
executional error: this occurs during executing the program.
Deffect: when the error is discovered by the tester then it
is called deffect.
bug:if the developer accepts the deffect then it is called
bug.

When there is a mistake in programming it is a ERROR
The error noticed/found by the tester is a DEFECT
When the defect is agreed by the programmer also then it is
a BUG.

Answer / hrishikesh
A mistake or fault done in the coding that makes error to
lead the program execution is called error..
If the error caught by tester then it is called as defect
or simply we can say the mismatch between actual and
expected result...
If the defect is accepted by the development people then it
is called as Bug.

Answer / ajay singh
Bug: it is inconsistancy netween Functional Requirement and
actual implementation. If something is already documented
to be implemented and implementation is not consistant as
per requirement then its a BUG.
Defect: If something is happening with the functionality
that is not mentioned in any document to be followed during
implementation or testing then its a defect.
Like if we double click on any Folder existing on the root
node and get an Internal Error or System Crash message then
its a Defect.

Answer / vivek
Error : It is the Deviation from actual and the expected
value. Errors are potential defects that are found during
the phase that created them.
Bug : It is found in the development environment before the
product is shipped to the respective customer.
Defect : It is found in the product itself after it is
shipped to the respective customer.
Errors = potential defects that are found during the phase
that created them, and
Defects = errors that escape to a subsequent development or
delivery phase.
