Grid Computing Vs Cluster Computing

A cluster computer is a set of CPU nodes that are used to solve any problem over a network. The way in which this cooperation is accomplished among the computers to solve a problem is called Cluster Computing. In Grid computing, the idea is very similar to Cluster Computing however they are used for solving large problems. Clusters are usually homogeneous and Grids are heterogeneous. Homogeneous is where all CPU nodes have the same Hardware configuration and OS. A cluster of clusters is usually a Grid. CPU nodes that are part of a Grid need not be homogeneous and are usually spread across LANs or WANs.
