RMAN = Recovery Manager. It's a utility to manage the backup and recovery of Oracle databases.

RAC = Real Application Clusters = a way to have many Oracle instances running against a single Oracle database. Think of a cluster of systems all accessing the same set of files. The old name for RAC used to be Oracle Parallel Server (OPS). Oracle marketing, however, prefers that we "think" of RAC as an entirely new product. Perhaps under the hood it is, but in concept RAC seems to me to be just an evolution of OPS.
