Quality assurance (QA) is about process.  It is the systematic establishment and monitoring of processes designed to improve quality throughout an organization.  The two major aspects of QA are 1) to ensure products and services are "fit for purpose" and that errors in processes are minimized. Code peer reviews, walkthroughs, and code inspections are examples of quality assurance. 

Quality control (QC) deals directly with a product or service.  It is a process through which quality performance is measured, compared it to standards, and actions are taken to close the differences. Test design, execution and defect reporting are examples of quality control.
