cluster
A group of computers that cooperate to achieve a common task. A cluster must meet the following criteria: first, the cluster must be composed of whole computers, called nodes. Second, no two nodes of a cluster should have incompatible versions of the same data; this is called consistency. Finally, a cluster must be named and used as a single computing resource.
