Distributed Computing systems :
. Are built over a large number of autonomous computer nodes.
. Nodes are connected by SANs, LANs, or WANs.
. A LAN >> working clusters.
. A WAN >> massive systems.

Computing Cluster:
Definition: a cluster consists of interconnected homogenous stand-alone computers which
work cooperatively as a single integrated system.
Cluster Architecture :
. System image (SI)
Single-System Image (SSI)
. Collection of resource as one integrated, powerful resource
. Make the cluster like a single machine to the user

Peer-to-Peer Systems:
. Every nodes act as a both client or server
. All client machines act autonomously to join or leave the system freely
. No central coordination or central database is needed (no master-slave relationship)
. No peer machine has a global view of the entire P2P system
