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.
Application servers
Application servers are used to describe any server that runs backend application services (for example, servers that host search crawl and query components).
Multiple redundant application servers can be load balanced
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
