Which topology allows each node to have a direct connection to every other node?

The topology that allows each node to have a direct connection to every other node is the Mesh Topology. In a Mesh Topology, every device on the network is interconnected, which enables robust communication between all nodes. This direct linking provides high redundancy, as multiple pathways exist for data to travel, enhancing the network's reliability and fault tolerance. If one connection fails, data can still reach its destination through other connected nodes.

Additionally, the Mesh Topology supports high data transmission rates since nodes can communicate directly with each other without needing to route through a central point, unlike some other topologies where all communications may pass through a central hub or a limited pathway. The comprehensive connectivity facilitates easier troubleshooting and enhances the overall performance of the network, making it an optimal choice for complex networking needs where reliability is crucial.
