Q

Describe the star topology

A

Multiple hosts are connected to a centralized box where frames are distributed by the central box, if one connection fails the other hosts are still able to receive frames

Q

Describe the Mesh topology

A

Every hosts is connected to every other host, creates fault tolerance - if one connection fails you can still connect via the other cables, not good for wired scenarios but good for wireless ones
