The nodes in a star topology are linked to a central hub or router, and information is routed from the central hub or router to all of the nodes. If there are n nodes, there are n links in Star topology. The nodes are completely connected to each other via a dedicated link through which information travels from node to node.

• The nodes in a star topology are linked to a central hub or router. The nodes in a mesh topology are completely connected to each other via a dedicated link.
• If there are N nodes, there are N links in Star topology. If there are N nodes, there are N(N-1)/2 links in Mesh topology.
• Star topology is less expensive. Mesh topology is prohibitively expensive.
• Star topology has a low level of complexity. Mesh topology has a high level of complexity.
