1)    What is MVC (Model View Controller):

·         MVC is a suitable architecture while developing web applications due to separation of concerns.

• Model (The business layer as Calculation, Validations, Database connectivity)-Via Model Classes
• View (The display(UI) layer)
• Controller (The input controller as Read datas from view, send input data to the model)

·         Model is the part of the application that handles the logic for the application data Often model objects retrieve data (and store data) from a database.

·         View is  the part of the application that handles the display of the data. Most often the views are created from the model data.

·         Controller is the part of the application that handles user interaction. controllers read data from a view, control user input, and send input data to the model.

·         The MVC separation also simplifies group development. Different developers can work on the view, the controller logic, and the business logic(Model) in parallel.

2)    What is Advantages of MVC (Model View Controller):

SoC – Separation of Concerns:
Separation of Concerns is one of the core advantages of ASP.NET MVC. The MVC framework provides a clean separation of the UI, Business Logic, Model or Data. Developer can work Independently.

separation of concerns, which means the code and .aspx page are tightly associated with each other. This creates errors when the developer attempts to change one without impacting other.

However, ASP.NET MVC has a separation of concerns, which means that one aspect or component can be changed without disturbing other..

More Control

The ASP.NET MVC framework provides more control over HTML, JavaScript, and CSS than the traditional Web Forms.

Multiple view support

Due to the separation of the model from the view, the user interface can display multiple views of the same data at the same time.

Lightweight

                        ASP.NET MVC framework doesn’t use View State and thus reduces the bandwidth of the requests to an extent.

 

Testability

ASP.NET MVC framework provides better testability of the Web Application and good support for test driven development too.

 

                        Change Accommodation

User interfaces tend to change more frequently than business rules (different colors, fonts, screen layouts, and levels of support for new devices such as cell phones or PDAs) because the model does not depend on the views, adding new types of views to the system generally does not affect the model. As a result, the scope of change is confined to the view.

Full features of ASP.NET

One of the key advantages of using ASP.NET MVC is that it is built on top of the ASP.NET framework and hence most of the features of the ASP.NET like membership providers, roles, etc can still be used.

 

3)    How many Return Type in action method (Model View Controller):

·       MVC There are total of nine return types we can use to return results from the controller to view.
