These are indicating to application/specific function is not working as per expectation. Depends on the companies these terms will be used. Some companies are using anomalies instead of bug/defect etc...

In generic way the main difference is :

Bug : At the time of developing or testing(i.e before releasing of s/w) the raised anomalies  are  treated as Bugs.

Defect : After s/w releasing whatever the anomalies raised, is called as Defect.

Error : The syntax problems, debugging problems which are relevant to coding are treated as errors.

Error - Occured during the devloper coding  time.

Defect - found by Tester during testing process is called a defect or issue.

Bug - mistake accepetd by developer to resolve is called a bug.
