Error-Mistakes in code of appication is error due to errors in coding.
Defects-Mismatches found by testers during testing of the application build are termed as defects.
Mismacthes three types
1. Mismatch between expected and actual
2. Missing functionality with respect to customer requirements
3. Extra functionality with respect to customer requirements.
Bugs-If defects are accepted by Developers to be solved are bugs.
Note:
some defects cannot be accepted as bugs by developers as they may be coming in future versions of the application.
While an error is an error in the program code, bug and defect are the interchangeable terms at my workplace.
Lack of WILL POWER has caused more failure than
lack of INTELLIGENCE or ABILITY.

Bug and defect are term used to define same thing.
Error is the problem due to bug/defect.

defect & bug are the terms used by testers. a variation in the expected and actuals is called a defect - as stated in the test case document during test execution. The defect recognised and accepted by developers are called bugs.
error - a mistake in the program (syntactical error, logical errors etc.,). a term used by programmers while coding.
