Concept

Network topology describes how nodes and communication links are arranged. In a full mesh, every distinct pair of nodes has a dedicated point-to-point link; a bidirectional link permits communication in either direction.

For n nodes, the number of physical links in a full mesh is n(n − 1)/2 because each link joins one distinct pair. This pairwise-connectivity rule distinguishes a full mesh from hub-based or hierarchical layouts.

Application

The stem states that every pair of nodes has a bidirectional link. That is the defining connectivity rule of a full mesh, so the required topology is Mesh topology.

Contrast and cross-check

• Star topology connects peripheral nodes through a central hub or switch rather than directly connecting every pair.

• Tree topology arranges nodes in parent-child branches across hierarchical levels.

• “None of these” would apply only if none of the named topology categories described the stated link arrangement.

• With four nodes, a full mesh has 4(4 − 1)/2 = 6 links, one for each node pair, which cross-checks the definition.

Result

The topology is Mesh topology.
