Answer:
Partial mesh topology
Explanation:
Mesh is a network topology that connects computers with to many obsolete network node interrelations. Each node has a link to every other node in the network in a real mesh topology.
Two kinds of mesh systems are available: full mesh and partial mesh.
Partial mesh topology is less costly than full mesh network to execute and produces less redundancy.
Some nodes are arranged in a complete mesh system with partial mesh, but others are linked in the network only a few.
