Answer:

a) Here, Total No. of subscribers=N

So, the total number of lines in the network, L = \frac{N(N-1)}{2}

b) If N=2, then L=1;

If N=10, then L=45;

If N=100, then L= 4950;

If N=1000, then L= 499500.

c) In a mesh topology network with N subscribers, (N–1) lines must be built to each subscriber.

d) No it is not suitable for a public telecommunications network.

Because it is costly and complex to implement. Needs more power to active all nodes. The nodes will face redundant connection problem etc.

Explanation:

a) Because each subscriber is directly connected to all other subscribers, the network follows a mesh topology.

b) If N=2,

L=\frac{2*(2-1)}{2} = 1.

If N=10,

L= \frac{10*(10-1)}{2} = 45.

If N=100,

L= \frac{100*(100-1)}{2} = 4950

If N=1000,  

L= \frac{1000*(1000-1)}{2} = 499500.
