Angular Interview Practice

What architecture does Angular follow?

1. Layered architecture

2. Service-oriented architecture

3. Component-based architecture

4. Microservices architecture

The correct answer is: Component-based architecture

Angular follows a component-based architecture, which is central to its design philosophy. This approach allows developers to create applications as a collection of loosely coupled, reusable components. Each component encapsulates its own functionality, including HTML templates, styles, and logic, which makes it easy to manage complexity by breaking down the user interface into smaller, self-contained parts. Components can communicate through inputs and outputs, enhancing reusability and maintainability. This architecture promotes better organization of code, leading to improved collaboration among developers, as different team members can work on separate components without causing conflicts. Overall, the component-based architecture facilitates the development of large-scale applications by enabling a modular approach, which is a significant aspect of Angular. Other architectural styles mentioned, while relevant in different contexts, do not accurately describe Angular's structure. For instance, layered architecture typically represents a more static design, where functionalities are separated into layers but do not offer the same level of reusability as component-based systems. Service-oriented architecture focuses on services as fundamental building blocks, which is more applicable to backend frameworks. Microservices architecture pertains to the deployment of applications as multiple small, independently deployable services, which does not align directly with Angular's client-side structure.
