Hi , i dint as yet get to chapter 7, but i would say that a hub is a passive device, as it just serves just as a wiring center between computers and other nodes in a LAN,

A switch on the other hand is a form of an intelligent HUB as when a pc's sends a data over the LAn , the switch regenerates this signal and sends it to the receiving end. so i would say a switch is active

Hub is just used to direct signals.

Thats just my opinion, i will repost once i research this topic

I think that there is more control over a LAN, as one can decide what types of messages the want to filter for security reasons, even who is allowed to access specific information, what type of hardware would be best for a specific operation
