基本解釋

Connecting several thousands of computers to a LAN can in theory be done using a star, a ring, or a bus topology.

The link layer topology discovery can discover the physical topology internal a LAN, which the network layer topology discovery can not discover.

It's always a good idea to purchase cables that are 1 or 2 times longer than the required length in case the structure (topology) of the LAN changes in the future.
