Regional Regression Testing is reexecuting the same test cases again in order to check whether the bug exists or not but the focus is also on the impact area that is affected because of the change in the application.
Unit regression testing Regional regression testing Full regression testing
Regression are classified as - Full / Complete Regression -- Entire application is regressed - Regional regression -- Tests performed around defect fixes or code changes
Regression testing.
regression testing is a white box testng
Just like that

To complete testing application if any modification done any modules or functionality that is called regression testing.

system testing is a kind of retesting where we can test whole system after integration. while regression testing is a process where we do the rerunning the test cases and check whether that re run doesnot affects the real environment.
Regression testing is an iterative process executed throughout the software development and testing cycle. Regression testing focuses on previously tested aspects, features which were tested and found working, or bugs which were found and confirmed fixed, in earlier versions of the software. The purpose of regression testing is to make sure that those previously verified features still work. For example, consider a software release that includes two new features, A and B. While the developers are still working on feature B, test is already examining feature A. When A is found working as planned, testing proceeds to feature B, while regression testing affirms that nothing in feature B broke A.
Regression testing is a type of software testing that seeks to uncover new software bugs, or regressions, in existing functional and non-functional areas of a system after changes such as enhancements, patches or configuration changes, have been made to them.
