Unmanaged as someone else said is plug and play.
Everything that's plugged in can communicate with everything else.
Managed means you can do fancy things, one of which is VLANs.
This means that you can have 2 (or more) completely separate networks plugged into the same switch.
If you have VLAN aware hardware, it can communicate with multiple networks off of one switch port.
A home application would be a power user using something like pfsense.
You'd plug your modem, your server, and all your clients into the switch. Normally this would be a disaster.
But here, your modem is on a separate network so only your server can see it. On the same line, your server is also "giving" internet to the other ports which are also isolated.
You could add stuff like guest networks too so a friend connecting to your wifi won't see your pr0n collection.
Managed isn't really that practical for home use, but it can be very beneficial if you're a power user.
Nope. That's why I'm on the internet arguing with strangers. If I had anything better to do I'd probably be doing it.Do you not have anything else to do rather than argue with strangers on the internet
