Answer Posted / anitha
Error : It is the human mistake done on the part of the
developers
Defect : Deviation or variation between expected result and
actual result
Bug : Defect and bug are almost same.the term bug which is
used in the place of defect.It is a informal term.
Fault : The error which has occured after completion of the
product
Failure : when the defect is visible to end users
Since we say
error,defect,bug - process related errors
fault,failure - product related errors
