i) Software Quality Assurance (SQA): This is a process which ensures that the developed software meets and complies with the defined or standardized quality specifications. It is an ongoing process within the software development life cycle (SDLC) that routinely checks the developed software to ensure it meets desired quality measures.

ii) Software Quality Control (SQC): This is a set of activities for ensuring quality in software products. The activities focus on identifying defects in the actual products produced. It is a strategy of the quality management system and is a reactive process. It involves activities such as testing, code reviews, and inspections to ensure the product is being developed correctly and meets the specified requirements.

iii) Software Audit: This is an independent examination of a software product or processes to assess compliance with specifications, standards, contractual agreements, or other criteria. It is typically conducted by a third-party organization, independent of the team that developed the software, to ensure objectivity.
