What is a two tier architecture?

A two-tier architecture is a software architecture in which a presentation layer or interface runs on a client, and a data layer or data structure gets stored on a server. Separating these two components into different locations represents a two-tier architecture, as opposed to a single-tier architecture.

Is MVC a 3 tier architecture?

Conceptually the three-tier architecture is linear. However, the [model-view-controller] MVC architecture is triangular: the view sends updates to the controller, the controller updates the model, and the view gets updated directly from the model. MVC is a pattern used to make UI code easier to maintain and test.

How many tier architectures are there?

Multitier Client/server Architecture. The three-tier architecture can be extended to n-tiers, with additional tiers added to provide more flexibility and scalability. Some distributed computing systems have more than three layers, but the basic rules are the same as those for three-tier applications.

What are the advantages of 3 tier architecture?
