Star topology networks are more scalable.
Star topology networks are less expensive to install.
Star topology networks are easier to install.
Star topology networks are more secure.
Performance over the entire network would suffer slightly.
Only the failed node would be unable to transmit or receive data.
Data could no longer be transmitted or received at any point in the network.
The failed node would broadcast errors to the rest of the network.
To reduce RF emissions that may result in security breaches.
To increase available bandwidth by sending multiplexed signals.
To arbitrade addressing conflicts between sending nodes.
To repeat signals to all nodes on the segment
A home network that connects two computers
A WAN that connects freelance writers across the nation
A LAN that connects a dozen computers in an insurance company
A WAN that connects multiple churches within a city
All nodes connected to that hub would be unable to communicate with nodes on other segments, but they could communicate with each other.
All nodes connected to that hub would be unable to communicate with nodes on other segments as well as nodes on their own segment.
Nodes would be able to communicate with the network, as they would automatically connect to an alternate hub on the backbone.
Communication on the entire LAN would halt.
Terminators are not used on star-wired networks
