    The fault which causes a software to work in an unintended way.

    The fault or problem which is caused after the release of the software to end-users.

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

    Ooops ... I was late by 2 mins.
    Anyway ... congrats Kshiteej :D :cheers:

    @ 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.
