Angular offers advantages such as two-way data binding, dependency injection, and modular architecture.

• Two-way data binding allows automatic synchronization of data between the model and the view, reducing the need for manual DOM manipulation.

• Dependency injection helps manage dependencies and promotes code reusability by allowing components to be easily injected with their dependencies.

• Modular architecture enables deve...read more

Design patterns are reusable solutions to common problems in software design.

• Design patterns help in creating flexible, maintainable, and scalable software.

• Some common design patterns include Singleton, Factory, Observer, Strategy, and Decorator.

• Singleton pattern ensures a class has only one instance and provides a global point of access to it.

• Factory pattern creates objects without specifying the exact class of object...read more

Delegates are type-safe function pointers in C# used for implementing callbacks. async/await is used for asynchronous programming in C#.

• Delegates in C# are similar to function pointers in C or C++. They allow methods to be passed as parameters to other methods.

• Async/await in C# is used for asynchronous programming, allowing methods to run asynchronously without blocking the main thread.

• Delegates can be used with async/

An interceptor is a design pattern commonly used in software development to capture and manipulate requests and responses.

• Interceptors can be used for logging, authentication, authorization, caching, error handling, etc.

• In Angular, interceptors can be used to modify HTTP requests before they are sent and responses before they are received.

• In Spring framework, interceptors can be used to intercept client requests and se

Authentication is the process of verifying the identity of a user or system.

• Authentication involves confirming the identity of a user through credentials such as passwords, biometrics, or security tokens.

• Common methods of authentication include single-factor authentication (e.g. password) and multi-factor authentication (e.g. password + SMS code).

• Authentication can be achieved through protocols like OAuth, OpenID, SAML...read more

Services in Android are components that run in the background to perform long-running operations.

• Services can be used to play music in the background while the user interacts with other apps.

• They can also be used to download files from the internet even when the app is not in the foreground.

• Services can run indefinitely or be scheduled to run at specific times.

• They can communicate with other components using broadcasts
