Service providers are the central place to configure and register application services. They bootstrap any application services upon the initialization of the Laravel container.
12) What is the difference between `get()` and `first()` methods in Eloquent?
`get()` retrieves a collection of results, while `first()` fetches the first result only. `first()` returns a single model instance or null if no record matching the query is found.
13) How can you define a route that accepts parameters?
You can define such routes by including curly braces in the URI: `Route::get('/user/{id}', ‘UserController@show’);` This captures the ID as a parameter.
14) What is CSRF protection in Laravel?
CSRF (Cross Site Request Forgery) protection in Laravel uses tokens to ensure that requests from authenticated users are valid, helping prevent unauthorized actions from malicious sites.

Localization in Laravel is managed through language files stored in the `resources/lang` directory. You can define translations in these files and retrieve them using the `__()` helper function.
28) What are form requests in Laravel?
Form requests are custom request classes that encapsulate validation logic and authorization, allowing you to separate the validation concerns from your controllers for cleaner code.
29) How do you handle file uploads in Laravel?
File uploads in Laravel can be handled using the `Request` object to retrieve the uploaded files, and you can store them using the `store()` method provided by the `Storage` facade.
30) What is a Resource Controller in Laravel?
