What is Cluster Computing?
Cluster computing is a form of computing in which a group of computers are linked together so that they can act like a single entity. There are a number of reasons for people to use cluster computers for computing tasks, ranging from an inability to afford a single computer with the computing capability of a cluster to a desire to ensure that a computing system is always available. The precise date at which this technique was developed is unknown, and there are competing claims for the invention credit, with some people suggesting that individual users probably developed cluster computing independently to meet their computing needs long before the technique was used in industrial settings.
