Regression Testing or Re testing?

Regression testing is the process to ensure the data are working properly with the existing software.  The main aim is to fix the bugs and to make sure the problems are solved.

Regression testing is acting as the control measure for maintaining the quality of the product with its specified requirements and the code. People often get confused over difference between regression testing and re testing.
