    Bug is the problem found at the developers site.

    When the developer doesnot correct/found it and reached to the tester and tester reports it it becomes error.

    And if it has reached to the customer and customer find it , then it becomes defect.

    Error : It is the Deviation from actual and the expected value.

    Bug : It is found in the development environment before the product is shipped to the respective customer.

    Defect :     It is found in the product itself after it is shipped to the respective customer.
