DEFECT :while Testing the application incase any mistakes 
in the application is called Bug. we will get Testers hand 
or developer place.

Clients developer place.

Interchanged the titles with same definition.They were 
wrongly placed,so definition varied.

defect - when developer devlope any type of application, at 
that time those mistake occur within development is called 
defect.

bug  - after development of project at the time of 
execution, any error occur then it is called as bug

Defect: it is a error or fault in the application after
delivery. it will be detected by the client or end users

Bug is is a error or fault in the application before
delivery of the product to the client or to the market.

Defect:The defect is an error which we are getting when we 
are using the application or performing some operation in 
the application.Code must be there in the program but it is 
not able to pass the value to the correct location or the 
code is forwarding a page for which nothing is written in 
the code.That is called a real time defect.

Bug:Bug is the run time exception,suppose we are going to 
fix a defect and during working on the defect we got an 
error such as a variable is using in capital letter or 
small letter that type of confusion or variable is not 
defined properly.That is specially called the bug.In this 
case our application may run or may not.But that is called 
a bug.

Well, I think that there is something else about it..

DEFECT
BUG
FAILURE

In this sense:

Defect - Is a not desired state found in documents, 
diagrams and even code but not discovered testing the 
application. A defect COULD anticipate a BUG and also avoid 
it.

BUG - A not desirable state of an application, found by 
excercise the system in an phase dedicated to that. 
(testing phase). If a BUG is not detected on time, it could 
raise a FAILURE.

FAILURE - Something wrong with the application but found 
after it was realeased and that fails some application 
requirement.

hi all, 

Error : when any mistake done by the devolopers during 
coding a requirement is called Error.

Bug: when an error has been found by the testers during the 
process of actual testing is called Bug.

Defect : when the bug has been accepted by the devolopers 
to resolve is called Defect.

iam requesting all , correct me if iam wrong .

Bug: A catch all term for all software defects or errors
Defect: It is “A deviation from specification or standard”
