What does network topology refer to?

Network topology refers to the physical or logical arrangement of different elements (links, nodes, etc.) within a network. This includes how various devices, such as computers, routers, and switches, are interconnected and how data flows between them. Understanding network topology is essential for designing efficient networks, troubleshooting issues, and ensuring that data can be transmitted effectively across different parts of the network.

The different types of network topologies, such as star, ring, bus, and mesh, each have their own advantages and disadvantages based on factors like scalability, complexity, and fault tolerance. Therefore, recognizing the arrangement of nodes is critical for network planners and administrators to optimize performance and maintain security.
