A regression test is a test where a previously known bug is tested for after a change. A retest is simply repeating a test.

sorry
Regression testing is intended to uncover any bug that may have been introduced in the application as a side effect of fixing some other bug. So all the test cases are run. This is different from Unit testing, where we run only unit tests for the unit where we fixed the bug. Stress testing stresses particular functionality so see where is will break etc. For example a good stress test for MS Word may be to open a file in MS Word and keep writing text to it till it breaks.
Regression testing is something every programmer should do after changing the code. Elderly individuals sometimes undergo a remarkable regression to a childlike state. The military's observers reported the regression of the country to a feudal state.

Retesting means testing the functionality or bug again to ensure the code is fixed. If it is not fixed, defect needs to be re-opened. If fixed, defect is closed. Regression testing means testing your software application when it undergoes a code change to ensure that the new code has not affected other parts of the software.
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.
Just like that

confirmation testing or Re-Testing: After a defect is detected and fixed, the software should be retested to confirm that the original defect has been successfully removed. This is called Confirmation Testing or Re-TestingRegression testing: Testing your software application when it undergoes a code change to ensure that the new code has not affected other parts of the software.
To complete testing application if any modification done any modules or functionality that is called regression testing.
