The V-model is a software development model that emphasizes the relationship between each phase of the development life cycle and its corresponding testing phase. It is called the V-model because of its V-shaped representation, with the left side representing the development phases and the right side representing the testing phases.

The V-model includes the following phases:

1. Requirements analysis: In this phase, the requirements for the software are gathered and documented.

2. System design: In this phase, the overall system architecture and design are developed based on the requirements.

3. Module design: In this phase, the detailed design of individual modules or components is created.

4. Implementation: In this phase, the code is written and the software is developed.

5. Unit testing: In this phase, each individual module or component is tested to ensure that it functions correctly.

6. Integration testing: In this phase, the modules are integrated and tested as a group to ensure that they work together properly.

7. System testing: In this phase, the entire system is tested to verify that it meets the requirements and functions as intended.

8. Acceptance testing: In this phase, the software is tested by end users to ensure that it meets their needs and expectations.

The V-model emphasizes the importance of testing throughout the development process and ensures that each phase is validated before moving on to the next phase. This helps to reduce the risk of defects and ensures that the software meets the requirements and quality standards.
