The correct option is Design. In the design phase of the SDLC, the software system's architecture, structure, modules, interfaces, and data flow are planned and documented. This phase bridges the gap between the requirements gathered and the actual implementation. It involves creating detailed technical specifications, such as system diagrams, database designs, user interface designs, and algorithmic designs. The design phase lays the groundwork for the development team to start coding based on the established design.

NoSQL databases commonly use JSON (JavaScript Object Notation) as a format for storing and retrieving data. JSON is particularly well-suited for NoSQL databases due to its flexibility, simplicity, and ease of integration with various programming languages and frameworks, making it a popular choice for developers working with these databases.

Data normalization involves structuring data in a database to reduce redundancy and dependency. This process ensures that each piece of data is stored in only one place and eliminates the potential for inconsistent information. It helps improve data integrity, reduce storage space, and streamline data retrieval and manipulation processes.

The Transport layer in the OSI Model is responsible for segmenting and reassembling data packets to ensure reliable and efficient communication between end systems. It also handles flow control, error checking, and data integrity to guarantee that information is delivered accurately.

When deciding between virtual machines (VMs) and containers for cloud migration, factors such as operating system dependencies and resource utilization play a crucial role. Virtual machines offer strong isolation and can run multiple operating systems, making them suitable for legacy applications with diverse OS requirements. Containers, on the other hand, are lightweight and share the host OS, leading to better resource utilization but may face challenges with legacy applications and persistent storage needs. Hence, understanding the specific needs of the applications in terms of OS dependencies and resource utilization is key to making an informed decision.

Stacks and queues find numerous real-world applications. For instance, in a text editor, a stack can be used to implement undo operations efficiently. Similarly, a queue can manage requests in a web server, ensuring fair handling based on arrival order.

The "D" in ACID stands for Durability, which ensures that once a transaction is committed, it will persist even in the face of system failures such as power outages or crashes. This is crucial for maintaining the reliability and resilience of a database system, as it guarantees that data modifications made by transactions are permanent and will not be lost due to unforeseen circumstances. Without durability, data could be lost or corrupted, leading to inconsistencies and potential data loss. Therefore, the importance of durability in ACID properties cannot be overstated, as it forms the backbone of data persistence and reliability in database management systems.

Cross-Origin Resource Sharing (CORS) is a crucial security mechanism that prevents malicious websites from accessing resources across different domains. By allowing servers to specify which origins can access their resources, CORS helps mitigate risks associated with cross-domain requests, such as cross-site scripting (XSS) and cross-site request forgery (CSRF). It enhances web security by enforcing browser restrictions and ensuring that only authorized domains can interact with sensitive data.

Resource preemption involves forcefully taking resources from processes that are deadlocked to break the deadlock situation. This is a technique used in deadlock handling in operating systems.

Demand paging is a virtual memory management technique where pages are loaded into memory only when they are required, thus optimizing memory utilization. When a process is initiated, only essential pages are loaded initially. As the process executes and requires more pages, they are fetched from secondary storage. This approach minimizes initial load time and allows for more efficient use of available memory.
