Network topology refers to the physical or logical arrangement of connections within a computer network. Bus, Star, and Mesh are common network topologies. Peer-to-Peer (P2P) is a network model or architecture, not a topology.

– **Bus Topology:** All devices share a single communication line (bus).
– **Star Topology:** All devices are connected to a central hub or switch.
– **Mesh Topology:** Devices are interconnected with point-to-point links. Can be full mesh or partial mesh.
– **Peer-to-Peer:** In a P2P network model, devices (peers) directly share resources without a central server. This model can be implemented over different underlying network topologies.

Other network topologies include Ring topology, Tree topology, and Hybrid topology (combinations of others). Peer-to-Peer describes the relationship and communication flow between nodes, not their physical or logical arrangement.
