When non-compliance with regulatory standards is identified in a software audit, it is crucial to collaborate with the relevant regulatory authorities to understand the specific issues and work on making necessary adjustments to bring the software into compliance. This may involve legal consultations and modifications to the software to meet the required standards. Ignoring or releasing the product as is can lead to legal and reputational risks.

Adherence to the Single Responsibility Principle (SRP) in software design means that each module or class should have a single reason to change. When this principle is followed, it simplifies code, making it easier to understand and maintain. Changes to one responsibility do not affect others, resulting in improved maintainability.

In white box testing, the "Code" is tested to check if it performs correctly. This involves checking that all statements and conditions in the code are tested, ensuring comprehensive code coverage.

Configuration Status Accounting in SCM is responsible for keeping track of all changes made to the system. It provides visibility into the status of the system's components and helps in monitoring and reporting on changes.

A key characteristic of Black Box Testing is that it is performed without knowledge of the internal code or system's internal logic. Testers focus on the inputs, outputs, and behavior of the software without delving into its implementation details.

In Agile development, prototyping often starts with building a "Vertical" prototype. This prototype includes a limited set of key features that provide a deep exploration of specific functionalities. It's not a final or complete product but serves to demonstrate essential aspects of the system.

In the Client-Server architecture, services communicate via a well-defined interface using lightweight protocols. This architectural style is characterized by the separation of client and server roles, where clients request services from servers, which can be located on different machines or networks.

The Microservices architecture style provides a structured system that can be decomposed into smaller, reusable modules. In this architecture, the software is organized into small, independent services that communicate through APIs. This approach allows for greater flexibility and scalability in software development.

Adaptive maintenance focuses on making changes to the software to adapt to changes in the operating environment, such as hardware upgrades or new regulations. It ensures the software remains compatible with evolving external factors.

The main focus of Black Box Testing is on the external behavior of the software, such as its user interface and functionality. Testers don't need to know the internal code structure but rather test the software as a "black box" without knowledge of its internal workings.
