Grid Computing

Grids enable the sharing, selection, and aggregation of a wide variety of geographically distributed computational resources (such as supercomputers, compute clusters, storage systems, data sources, instruments, people) and present them as a single, unified resource for solving large-scale compute and data intensive applications. This idea is analogous to the electric power network (grid) where power generators are distributed, but the users are able to access electric power without bothering about the source of energy and its location.
