Regression testing means it is the type of testing in which one will conduct testing on an already tested functionality again and again.
Regression testing will be conducted in two situations.
1.  If the test engineer find any defect on one functionality then after the rectification of that defect from the development department, again testing on that defected functionality and retesting the related functionalities of that defected functionality.

2. If the new features are added to that application, testing on that new feature functionality and also the related functionality of that new features to be tested.

Known regression testing occurs when functionalities are selected based on defects that were discovered in previous builds.  Functionalities that interact with the previously defective module may also become defective and running regression tests on these modules will help detect any defects that may exist in these vulnerable areas.

Another somewhat lesser form of known regression testing occurs when functional areas that are considered mission critical are targeted for testing.   

Unknown regression testing occurs when no criteria is used to isolate or target individual areas and testing is performed across all functionalities of the product.
