What is Cluster (computing)?
[[File:Us-nasa-columbia.jpg|thumb|A cluster of computers at [[NASA]]]] In computing, a '''cluster''' is made of many individual computers that work together to solve a problem at hand. Clusters can have different forms: They can be whole computers working together, or only [[CPU]]s. These CPUs can communicate over a fast network, but they share the same [[hard disk]]s, for example. Depending on the problem, solving it with a cluster of cheaper [[component]]s can be less expensive that investing in better hardware that costs more. [[Grid computing]] is different in that the individual computers work on separate tasks that are part of a large problem. They are usually more different from one another and geographically further apart than cluster computers are. {{tech-stub}} [[Category:Computing]]
