A4: Dependency injection is a design pattern that allows the removal of hard-coded dependencies, making the application easier to manage and test.

A5: Aspect-oriented programming (AOP) is a programming paradigm that allows the separation of cross-cutting concerns, such as logging and security, from the business logic.

A6: Spring handles transaction management through its declarative and programmatic transaction management support, allowing developers to manage transactions consistently across different data access technologies.

A7: Spring beans are objects that are managed by the Spring IoC (Inversion of Control) container, which handles their lifecycle and dependencies.

A8: A Spring application can be configured using XML configuration files, Java-based configuration (using @Configuration and @Bean annotations), or a combination of both.

A1: In Module 2, you will learn about the basics of Spring Boot, its features, and how to create Spring Boot applications.
