No difference; they are both logic errors within the software.

Ooops ... I was late by 2 mins.
Anyway ... congrats Kshiteej

@ shabbir :
Probably Mridula meant that,

Bug is an unintended behavior of the program (though it meets the customer's specs).
Defect is a missing functionality in the program, so it doesn't meet the customer's specs.
Mridula like this
