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 CPUs. These CPUs can communicate over a fast network, but they share the same hard disks, for example. Depending on the problem, solving it with a cluster of cheaper components can be less expensive that investing in better hardware that costs more.
