Question

which topology used internet

Answer 1

Internet architecture is organized into several planes. The data plane represents how data is actually forwarded between routers. Topologies based on the data plane reflect physical nodes and connections but these topology graphs are hard to create and harder to validate for correctness or completeness. The control plane represents how ISP's create and configure organizational routing policy. While the data plane is responsible for forwarding data based on policy, the control plane is responsible for configuring policy. As far as topology is concerned, nodes in this plane are autonomous systems, (AS) and links between nodes represent some type of relationship. There are two types of relationships. Customer-Provider links involve one AS providing Internet access to a smaller AS at a monetary cost. Peering links are agreements between two AS networks to exchange certain types of traffic free of charge. These types of Internet topologies have become a hot area of research in academia. There is a third less known plane called the management plane but the topology maps it produces are incredibly inaccurate since its data can be directly modified by network operators with no effects on routing dynamics.Use the integral and derivative to derive the Work-Energy Theorem or what I prefer to call the Net Work-Kinetic Energy Theorem. This is an AP Physics 1 topic.
