Please be patient with me, I am new to networking and trying to understand. So, we have 3 computers with the same subnet mask, 255.255.255.0 and the same default gateway, 192.168.12.1 connected to a switch, and the first two have the same network address and the third one, a different network address, 192.168.12.113, 192.168.12.205, 192.168.112.97. Can these computers communicate with each other? If not, why not?
