Most networks use intermediate systems to reduce cabling costs and complexity. In this topic, you will summarize the functions of hub, bridge, and switch appliances working at the Physical and Data Link layers.
As you study this lesson, answer the following questions:
- A host on a network sends a frame to the hub. Which other devices on the network will see this frame?
- A host on a network sends a frame to a switch. Which other devices on the network will see this frame?
- What are the similarities and differences between a bridge and a switch?
- What are the advantages of using switches instead of hubs?
- What is the difference between a managed and an unmanaged switch?
