I‘ve been trying to figure out why a router is needed. I know a router can be used for DHCP and some other things, but I’m just thinking of networking with static IPs. So the following:
Is it possible to do the following with static IPs:
Modem -> Switch -> PCs
Or do you need to go:
Modem -> Router -> Switch -> PCs
So what exactly does a router do and why is it needed?
