A '''computer cluster''' is a set of [[computers]] that work together so that they can be viewed as a single system. Unlike [[Grid computing|grid computer]]s, computer clusters have each [[Node (networking)|node]] set to perform the same task, controlled and scheduled by software.

The components of a cluster are usually connected to each other through fast [[local area network]]s, with each [[Node (networking)|node]] (computer used as a server) running its own instance of an [[operating system]]. In most circumstances, all of the nodes use the same hardware<ref>{{cite web|url=https://stackoverflow.com/questions/9723040/what-is-the-difference-between-cloud-grid-and-cluster|title=Cluster vs grid computing|website=[[Stack Overflow]]}}</ref>{{better source needed|date=June 2017}} and the same operating system, although in some setups (e.g. using [[Open Source Cluster Application Resources]] (OSCAR)), different operating systems can be used on each computer, or different hardware.<ref name=pcauthority>{{cite web|url=http://www.pcauthority.com.au/Feature/306972,weekend-project-build-your-own-supercomputer.aspx|title=Weekend Project: Build your own supercomputer|date=29 June 2012|first=Darien|last=Graham-Smith|website=PC & Tech Authority|access-date=2 June 2017}}</ref>
