Topology

In networking, Topology refers to the arrangement or layout of various elements (links, nodes, etc.) in a computer network. It defines how different nodes are interconnected and how data flows between them. Common network topologies include:

  • Bus Topology: All devices are connected to a single central cable.
  • Star Topology: All nodes are connected to a central hub or switch.
  • Ring Topology: Each node connects to exactly two other nodes, forming a circular pathway.
  • Mesh Topology: Nodes are interconnected with many redundant connections.
  • Tree Topology: A hierarchical topology with a root node and branching nodes.

Understanding network topology is crucial for network design, performance optimization, and troubleshooting.
