Quick Primer - Ethernet is a bus protocol, multiple devices can be on the same electrical cables. Although the vast majority of ethernet you will see is point-to-point links, it's important to remember this
The more logic, switching, throughput, and power delivery something has, the more energy it consumes and the more heat it needs to dissipate.
Managed Switch - Allow for fine grained control of ports, which traffic goes where, manually turning things on and off, vlans, etc... more then just a MAC address lookup table.
The interface for switches and routers can be serial ports and CLI, all the way to fancy web guis. Usually the more pretty the interface the less flexible it is and the more basic the functionality it delivers.
Thanks for the primer. Posts like this mean so much to me. Honestly, thank you.
