A '''grid network''' is a [computer network](/source/computer_network) consisting of a number of computer systems connected in a grid topology.

In a regular grid topology, each node in the network is connected with two neighbors along one or more [dimension](/source/dimension)s.  If the network is one-dimensional, and the chain of nodes is connected to form a circular loop, the resulting topology is known as a ring.  Network systems such as [FDDI](/source/Fiber_distributed_data_interface) use two counter-rotating [token-passing](/source/token-passing) rings to achieve high reliability and performance.  In general, when an ''n''-dimensional grid network is connected circularly in more than one dimension, the resulting network topology is a [torus](/source/torus), and the network is called "toroidal".  When the number of nodes along each dimension of a toroidal network is 2, the resulting network is called
a [hypercube](/source/hypercube).

A [parallel computing](/source/parallel_computing) cluster or [multi-core](/source/multi-core) processor is often connected in regular interconnection network such as a

a [hypercube graph](/source/hypercube_graph),
a [hypertree network](/source/hypertree_network),
a [fat tree](/source/fat_tree) network,
a [torus](/source/torus), or [cube-connected cycles](/source/cube-connected_cycles).

A grid network is not the same as a grid computer or a [computational grid](/source/computational_grid), although the nodes in a grid network are usually computers, and [grid computing](/source/grid_computing) requires some kind of [computer network](/source/computer_network) or "universal coding" to interconnect the computers.
