9.2.1 Network topologies

• Network topology refers to the arrangement of the physical and logical components
• Physical topology refers to the actual arrangement of devices and cables.
• Logical topology describes the physical layout of the network.

  False
• Match the network topology with its arrangement:

  Star ↔️ Central hub connected to all devices

  Bus ↔️ Single cable connecting all devices

  Ring ↔️ Devices connected in a circular chain

  Mesh ↔️ Every device connects to every other device

  Tree ↔️ Hierarchical structure with branches
• Order the following topologies from simplest to most complex in terms of setup:

  1️⃣ Bus

  2️⃣ Star

  3️⃣ Ring

  4️⃣ Tree

  5️⃣ Mesh
• Match the topology with its key characteristic:

  Star ↔️ Single point of failure

  Bus ↔️ Limited bandwidth

  Ring ↔️ Failure affects all devices

  Mesh ↔️ High redundancy

  Tree ↔️ Scalable hierarchical structure
• A bus topology is easy to troubleshoot due to its centralized management.

  False
• Network topology refers to the arrangement
• Physical topology describes the physical layout of devices and cables.
• Physical topology describes the physical layout of devices and cables
• A logical topology describes how data flows through the network.
• Match the network topology with its benefit:
