Question 26. Explain the concept of the MVC (Model-View-Controller) design pattern. How does it facilitate modular software design?

MVC separates an application into three interconnected components: Model (data and business logic), View (user interface), and Controller (handles user input and updates the model). It facilitates modular design by isolating concerns and promoting code reusability.

Example:

Implementing an MVC architecture in a web application with separate classes for the model, view, and controller.

Question 27. What are the phases in Software Engineering?

• Requirements gathering and analysis: This involves understanding the needs of the users and stakeholders, and translating those needs into a set of requirements that the software must meet.
• Design: This involves creating a blueprint for the software, including the overall architecture, the user interface, and the data structures.
• Implementation: This involves writing the actual code for the software.
• Testing: This involves verifying that the software meets the requirements and is free of defects.
• Maintenance: This involves updating and fixing the software as needed, and responding to user feedback.
