Architecture is a pattern on which application is built
also you can say its a blue print for every thing like design,coding,deployment, quality etc.
example : n tier architecture
Service Oriented Architecture
client server architecture
MVC
MVP
etc.
In This architecture different layer are found
like UI Layer
Bussuness Layer
Data Layer
Common Layer
etc.
Data transfer take place in layers in a different way on the architecture basis.
For N-tier See the following link

For Servive Oriented See the following Link
http://www.service-architecture.com/
For MVC see the following Link
http://www.beansoftware.com/ASP.NET-Tutorials/MVC-Architecture-Model.aspx
Etc.

Hi,
The terms tier and layer are frequently used interchangeably, but actually there is a difference between them: Tiers indicate a physical separation of components, which may mean different assemblies such as DLL, EXE etc on the same server or multiple servers; but layers refers to a logical separation of components, such as having distinct namespaces and classes for the Database Access Layer (DAL), Business Logic Layer (BLL) and User Interface Layer (UIL). Therefore, tier is about physical separation and units of deployment, and layers are about logical separation and units of design.
Creating a multi tier project design is more suitable and advisable to mid to large-size projects, whereas a good multi-layered design is suitable for small to mid-size projects.

Thanks&Regards
