In general, a cluster refers to a two machine setup where one is active and other is passive (or active/active in a true cluster environment).  The actual  processing is handled by only one machine while the other is on standby.  When the active machine goes down, the passive node takes over.

In a farm, all nodes are active – with traffic being distributed across them (as in the case of a web app).

Typically, Databases use Cluster terminology – and web applications prefer farms.
