Quality Assurance(QA):- QA is refers to set of planned and systematic activities that ensures that process in the organisation meets certain standards like ISO 9000 or SEI CMM level that gives certain degree of confidence in the quality of software being released.

Quality Control(QC):- QC is the process where product is actually executed and actual behaviour is compared with expected behaviour. All types of testing like white box and black box testing comes under quality control.
It is oriented to "detection".

Quality Assurance:

A set of activities designed to ensure that the development and/or maintenance process is adequate to ensure a system will meet its objectives.
 

QA activities ensure that the process is defined and appropriate. Methodology and standards development are examples of QA activities. A QA review would focus on the process elements of a project - e.g., are requirements being defined at the proper level of detail.

 

QA is process oriented

Quality Assurance makes sure you are doing the right things, the right way.

Quality Control:
 

A set of activities designed to evaluate a developed work product.

QC activities focus on finding defects in specific deliverables - e.g., are the defined requirements the right requirements

 
QC is product oriented
 

Quality Control makes sure the results of what you've done are what you expected.
