Question about Compaq NETELLIGENT 3024 24-PORT 10BASE-T UNMANAGED SEGMENTABLE RPTR (282532001)

1 Answer

Calculate network topology cost

1.Given that there are 5 nodes in a LAN and a connection between each pair of nodes is
$10. Based solely on the price of connections, how much would a full mesh topology

2.Given that there are 5 nodes in a LAN and a connection between each pair of nodes is
$10, how much would a ring topology cost?

3.If the 8-port 10BaseT hub is replaced by an 8-port 10BaseT switch, how many
pairs of PCs, in the 6-PCs LAN, can be communicating with each other through
that 8-port 10BaseT switch at a time, under the most ideal condition?

4.How many pairs of PCs, in the 6-PCs LAN, can be communicating with each
other through that 8-port 10BaseT hub at any one time?

5.State a topology that would be cheaper than the ring topology. How much would this
topology cost using the same $10 per connection for each pair of nodes, based on 5
nodes in the LAN?

We used our Dynex successfully for several months (serving 2 computers) and then, after a big thunderstorm the other night, now Computer 1 internet will only work when plugged directly to the modem....

Thanks for your question.

Given that one computer works and the other does not would tell me to change out cable to see if it fixes the issue, if not then the switch would be the issue on that particular side. Nine times out of ten its the cable itself.

Whichever the case may be you still would be recommended to try another Ethernet cable. Now the lan card inside the computer 2 should also light up when connected, so I would pay close attention to the lan card as well.

Thanks for your questions, We work for your Feedback and ratings, so dont forget to leave some feedback before you leave.

Best of luck

I am connecting 4 nodes through 2 switch located at 400ft distance. the data transfer is not working. 2 nodes are connected to each switch, both nodes connected to individual switch communicates with each...

Just to clarify, you have 4 computers connected to two ethernet switches. Two computers are connecteh to each ethernet switch and a network cable connecting the two ethernet switches 400ft apart.

For all the computers to communicate with each other, they all need to be in the same workgroup "name".
The cable joining the two ethernet switches need to be connected to the RJ45 UPLINK port on both the ethernet switches, and the uplink port may have a switch (the switch allows it to function as a standard RJ45 port or a RJ45 uplink port).
If there is no RJ45 uplink ports on the ethernet switches then a cross over network cable is needed to connect the ethernet switches together.

Irratic behaviour of the switch network

Well 1 can tell you that if I remember right with cisco networking the maximum number of swiches possible between two hosts in a LAN network is 7.
Try to imagine a line with 2 pc at the end points. You can put maximum 7 swiches between them or expect problems.
I suggest you to try to make a current network map if you don't have one already.
Than do some counting between points just like the way your routing protocol is managing the packets route and see how many swiches you hit.

You can read about a very similar kind of incident with brand new CISCO equipement over here.

Maybe the problem's root is something else, but what you wrote was giving me this idea first to think of.
Hope I gave you an idea.

Switches, hubs or routers typically are used in a star topology connection, so if one device fail everything else is still working. Everithing is managed inside but not like a bus topology system. You may need to use a tree topology in some case, keeping in mind the consequence of a failure.
