STATE & FAQ ON TOPOLOGYThis topology description of a network can also include or imply the nature of the data flow through the network. And practical term used in professional training.
💡 Ring topology is a network topology that combines two or more different types of network topologies, such as star, bus, ring, mesh, or tree, into a single network structure. It is designed to take advantage of the strengths of each topology while reducing their limitations. In a hybrid topology, different sections of a network may use different topologies depending on the requirements of the infrastructure, such as scalability, performance, and reliability. For example, an organization may use star topology within departments and connect those departments through a ring or mesh backbone. Hybrid topology is commonly used in large networks like enterprise infrastructures, data centers, and smart city networks because it provides flexibility, easier expansion, and better fault tolerance.
# INTERVIEW PREP GUIDE ABOUT HYBRID NETWORK TOPOLOGY (PHYSICAL & LOGICAL)
