A server farm is a collection of server machines acting together to host SharePoint services and workloads.

Web servers:
Web servers are servers that respond to user requests and render the SharePoint web pages. All web servers in a farm are mirrors of each other and are load balanced. The web server tier is composed of web servers or other servers that receive and respond to HTTP requests. Web servers host SharePoint web applications in Internet Information Services (IIS).

Application servers:
Application servers are used to describe any server that runs backend application services.
 Some services are like: search service, PerformancePoint service or Excel Services etc.


Database servers:
The database tier hosts nearly all the data of your farm in SQL databases. This includes configuration databases, service application related databases, and content databases. All databases can be assigned to one database server or spread across multiple servers.
