Quality assurance and Quality control in software testing
Quality Assurance is all about preventive activities, whereas Quality Control focuses on corrective processes. QA is the responsibility of everyone involved in the process, whereas QC is the domain of a specific team (of testers).
Still, all these activities are deeply intertwined. Quality Control is a subset of QA. Software testing is a subset of Quality Control.
