Final answer:
A full mesh topology is a network topology where each node has a direct physical connection to every other node.
Step-by-step explanation:
A network topology in which each node has a direct physical connection to every other node is known as a full mesh topology. In a full mesh topology, every node in the network is connected to every other node, creating a fully interconnected network. This type of topology allows for high reliability and fault tolerance, but it requires a large number of connections and can be expensive to implement.
