In both..QA is nothing but Varification i.e. static testing and QC comes under validation i.e dynamic testing

Testing contains many activities other than execution. When we consider the testing life cycle the following are the phases:
1. Test Planning and control
2. Test analysis and design
3. Implementation and execution.
4. Reporting and closure activities
QA-Quality assurance: contains the activities that are performed to measure the quality for example:test execution,reporting etc.
QC: Quality control: It consists of necessary measures that are taken to maintain the quality when deviated.
Example: planning.

Quality Assurance:
1. A planned and systematic set of activities necessary to provide adequate confidence that
requirements are properly established and products or services conform to specified
requirements.
2. An activity that establishes and evaluates the processes to produce the products.
3. Helps establish processes.
4. Sets up measurements programs to evaluate processes.
5. Identifies weaknesses in processes and improves them.
6. QA is the responsibility of the entire team.
7. Prevents the introduction of issues or defects
8. QA evaluates whether or not quality control is working for the primary purpose of determining
whether or not there is a weakness in the process.
9. QA improves the process that is applied to multiple products that will ever be produced by a
process.
10. QA personnel should not perform quality control unless doing it to validate quality control is
working.

Quality Control:
1. The process by which product quality is compared with applicable standards; and the action
taken when nonconformance is detected.
2. An activity which verifies if the product meets pre-defined standards.
3. Implements the process.
4. Verifies if specific attribute(s) are in a specific product or service
5. Identifies defects for the primary purpose of correcting defects.
6. QC is the responsibility of the tester.
7. Detects, reports and corrects defects
8. QC evaluates if the application is working for the primary purpose of determining if there is a flaw
/ defect in the functionalities.
9. QC improves the development of a specific product or service.
10. QC personnel may perform quality assurance tasks if and when required.

Hi Ritu!
You have delivered a good conceptual difference between QA and QC.

So far as difference between QA and QC in context to duties and responsibilities
members may refer to the reply of Kamalnath's reply on discussion on QA nd QC.

IF we combine Kamalnath's and Ritu's reply we arrive at a in- depth difference between QA and QC.

I thank both KAMALNATH and RITU.

Keep going on to participate technically like this.

Testing always comes under QC.

Quality Control : This is process of finding, fixing and preventing defects in the application. Generally QC is Process based.

Quality Assurance : This is to verify that all the declared process are been followed through out the Software development life cycle. Generally QA is process based.
