Detailed explanation-1: -Suppose that a number N of devices are connected to each other in a mesh topology, then the total number of dedicated links needed to connect them is N C 2, that is, N (N-1)/2. In Figure 1, there are 5 devices connected to each other, so the total number of links needed is 5*4/2 = 10.
Detailed explanation-2: -4 Answers. Since each two host need a cable so n(n-1)/2 cabels needed.
Detailed explanation-3: -FULL MESH TOPOLOGY If the network has n nodes, there will be (n-1) connections accordingly.
Detailed explanation-4: -In a fully-connected mesh network with 10 computers, total number of cables are required and number of ports are required for each device. ∴Total Number of cables = 10(10 – 1) / 2 = 5 * 9 = 45 cables.
