In data storage, the smallest amount of disk space that can be allocated to hold a file. All file systems used by Windows organize hard disks based on clusters, which consist of one or more contiguous sectors. The smaller the cluster size, the more efficiently a disk stores information. If no cluster size is specified during formatting, Windows picks defaults based on the size of the volume. These defaults are selected to reduce the amount of space that is lost and the amount of fragmentation on the volume. Also called an allocation unit. In computer networking, a group of independent computers that work together to provide a common set of services and present a single-system image to clients. The use of a cluster enhances the availability of the services and the scalability and manageability of the operating system that provides the services.

count to infinity
A loop that happens when a link in a network goes down and routers on the network update their routing tables with incorrect hop counts. For example, a loop can develop if the link to Router C goes down. Router B then advertises that the link is down and that it has no route to C. Because Router A has a route to C with a metric of 2, it responds to Router B and sends its link to C. Router B then updates its table to include a link with metric 3, and the routers continue to announce and update their links to C until they reach the number 16. This is a count to infinity.
