I was just thinking,...with Ethernet,...isn't there a limit on how many
Repeaters (hub) or how many bridges (switches) can be chained together
before it fails? I know each link with cooper has a 300 foot (100 meters)
limit, but I thought there was also a limit to how many repeaters and/or
bridges could be in the path as well when working in the context of a LAN.
