Is there any diff. between Bug,Defect,Error?

Answer Posted / ashwin kumar v n

DEFECT is introduced into the software as a result of an
ERROR at the input that may cause the system to behave
incorrectly and not according to the specification.

Error: It is a mistake,misconception or misunderstanding on
the part of a software engineer. When mistakes or errors
occur at the input side then they enter into the system as
faults/defects which further lead to the FAILURE of the system.
