Answer
# 3
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.

There is no difference in these terminologies unless 
specified by the management of your particular company. 
There have been many different assignments of meanings to 
each of these terminologies and you may find that where you 
work, there is a difference, but globally there is none.

Bug is software error which is not properly working in the 
application.
Defect is any one of these..
either insufficient in the SRS,
insufficient in DD's(Design Documents)
it may be any defect right from beginning of the 
development life cycle.
Error means it is mistake done by the programmers.
