Regarding to the Calculaiton of total number of links:Question 1

In full mesh network, each device has a n-1 number of connections.
And there is a total of n(n-1)/2 number of connections.

 Formula  n(n-1)/2  n-1 No. of links =8(8-1)/2=28 No of I/O Ports =(8-1)=7

Case Transmission Mode
Monitoring through Surveillance Camera Simplex

Talking through Walkie-talkie Half Duplex

Phone call through smart Cell phone Full Duplex

Real time high speed Audio-Video Conferencing Full Duplex

Monitoring through Surveillance Camera is a one way communication in which camera only captures video and pass it to DVR or directly to monitor if attached directly. Camera didn't receive packet/traffic from DVR or monitor. So it's Simplex

In case of Real time audio-video conferencing traffic can flow from both sides at same time. Both persons can speak and hear each other at same time. So it's Full Duplex communication.

n(n-1)/2

n-1

No of I/O Ports =(8-1)=7

Oh right. next time i will briefly explain it, I guess it was my first time.

Formula= n(n-1)/2
Nodes = n = 8
= 8(8-1)/2
= 8(7)/2
=56/2
= 28 28
