What the advantages and disadvantages for Tree network typology?
Advantages: Easy to expand the network.
Disadvantages: If the top node is impacted, all devices below it are be impacted.
What the advantages and disadvantages for hybrid network typology
The advantages and disadvantages depend on the types of networks combined.
What the advantages and disadvantages for Ring network typology
Advantages:
- Simple to build.
- Does not require a central node to manage data transmission.
- Adding devices to the network is easy.
Disadvantages:
- If any one device goes down, the entire network is affected. In other words, every device is a point of failure.
- Latency is variable between devices on the network. For example, devices near one another will trade data quickly, but devices far away will experience high communication delay.
