An RFC, or Remote Function Call, describes an external interface to a system function module available in SAP. For example, getting the system parameters is a system function available via RFC.

A BAPI, or Business Application Programming Interface, is an RFC-enabled function module that provides external access to an SAP business application such as creating a sales order.

In effect, all BAPIs are RFCs but there are a superset of RFCs that are not considered BAPIs. Really, two sides of the same coin.
