But in my view This thing makes life easier & distributed Just like a ATM machine which is a UI (presentation layer) connected to server
Business logic layer :- ATM functionality can be changed just by modifying Logic at one place i.e BL
Finally, the user info stored at centralized location called Database .. So with help of BL you can retrieve the required and particular records .. Data Layer

1) UI layer/Presentation layer - this layer will deal with the visual representation of your application. Like creating forms, web pages etc
2) DAL/Data Access Layer - this layer will deal with database related and other data related part. Like CRUD operation
3) Business Layer - this will deal with business entities and will contain validation logic as per requirement.

3-tier is basically the physical separation of your system components
There is another concept of layer or say 3 layer, where a layer is logical separation of your components of a system.
For ex : An n-tier application is usually like you web application running at the front end, in a browser, your code hosted in the IIS and database as a separate entity, So these different components basically act as a TIER.
N-layer is like you have a web application with different layers of code in it like BLL, DAL etc. layer. These layers can interact with each other for logical processing and usually they are on the same physical location(or you can say TIER). So BLL, DAL etc. act as the LAYERS.
So the concept of Tiers is not specific to C#. Its the more of type of overall architecture of the system.
