The term n-tier is a common industry term relating to a design tha is multi-layered (a quick google serach will give you lots of info https://www.google.co.uk/search?q=ntier+architecture&sourceid=ie7&rls=com.microsoft:en-GB:IE-Address&ie=&oe=&gfe_rd=cr&e… )
The Tableau Server whitepaper https://www.tableau.com/sites/default/files/media/whitepapertableauforenterprise.pdf discusses the structure more and includes this diagram, which shows the tiers in a the server enterprise design.

N-tier is another term for multitier, the tiers are the key
a 3 tier architecture would be as below (source: Multitier architecture - Wikipedia )
Data tier = the existing data store (Oracle, Hadoop etc.)
Logic tier = Tableau desktop, where the data is extracted, manipulated etc.
Presentation tier = Tabelau desktop, but more likely Tableau Server, Public and/or Reader
(this is also where security is handled in T Server)
This structure allows for flexibility and benefits through interchangabilty and reuse.
Hope togther with Donna's great answer that helps.

A 3-tier application is an application program that is organized into three major parts, comprising of data access layer tier at the bottom, the application tier (business logic) in the middle and the client tier (Presentation) at the top and each tier is distributed to a different place or places in a network. These tiers do not necessarily correspond to physical locations on various computers on a network, but rather to logical layers of the application.
