n


n1


n(n1)/2


One backbone and n drop line

Detailed explanation1: 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 (N1)/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 explanation2: 4 Answers. Since each two host need a cable so n(n1)/2 cabels needed.
Detailed explanation3: FULL MESH TOPOLOGY If the network has n nodes, there will be (n1) connections accordingly.
Detailed explanation4: In a fullyconnected 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.
