Re: two subnets thru same wire

Q1 and Q2: Yes, as long as each pair is using the same subnet mask ( such as 255.255.255.0).

Q3: There should not be any problems. The hub will pass all of the traffic going into it on all ports though.

Q4: Using a switch would work as well, but it will improve bandwidth utilization, since it can route packets to their destination port instead of just retransmitting the packets on all of it's ports like a hub.

My question realtes the fact, whether we can have two
subnets passing thru same wire and communicating with
each other. The two subnets are:
                  -----------------
                  |     Hub       |
                  -----------------
                   |    |   |   |
  -----------------     |   |   ---------------
  |              -------    -------            |
  |              |                |            |
  192.168.10.3   |                |       192.168.11.5
      A      192.168.11.3      192.168.10.5    D
                  B                 C

   It is a six port Hub. Four hosts with IP addresses
given above are attached to the hub. There are two
subnets 192.168.10.0 and 192.168.11.0.
The netmask is 255.255.255.0 in all cases.

Q1: Will Host A be able to talk to Host C?
Q2: Will Host B be able to talk to Host D?
Q3: If the communication is possible, are there likely
to be any problems?
Q4. If instead of switch, we use hub, will it make any
difference?
