Q

What are the main benefits to star topology?

A

Fault tolerance and scalability.

It is more fault tolerant; a cable disruption only affects one machine. It is also far more scalable; simply run a new cable.

Q

Why isn’t Ring Topology used anymore?

A

it’s not fault tolerant, difficult to reconfigure and troubleshoot, and expensive.

Q

Why isn’t mesh topology used in corporate LANs anymore?

A

It is complicated to manage, as every device on the network must be directly connected if it is a true mesh topology. This is why a hybrid mesh is usually used on modern WANs.
