Multitier architecture

Multitier architecture is like a big cake that is made up of many layers. Each layer has a different job to do.

The first layer is called the presentation layer, and it's the layer you see and interact with. It's like the frosting on a cake. This layer is responsible for how the cake looks and feels.

The second layer is called the application layer. It's like the cake itself. This layer is responsible for the main functions of the cake, like how it tastes and what kind of cake it is.

The third layer is called the data layer. It's like the ingredients in the cake. This layer is responsible for storing and managing all the data that the cake needs to work properly.

Multitier architecture is used in big programs and applications. It's like a big cake that has different layers. Each layer has a different job and responsibility. The layers work together to make the program or application work properly.
