Distributed Computing
Peer-to-Peer Computing
Many others: Cluster Computing, Network Computing, Client/Server Computing, Internet Computing, etc...

People often ask: Is Grid Computing a fancy new name for the concept of distributed computing?
In general, the answer is “no.” Distributed Computing is most often concerned with distributing the load of a program across two or more processes.
