Question 5 Explanation:
Fully connected mesh network, it means it is complete graph. We have standard formula to find total number of cables.
Here, n=10(total number of computers)
= n(n-1) / 2
= 10(9) / 2
= 45
→ To accommodate that many links, every device on the network must have n-1 input/output(I/O) ports
n=10(total number of computers)
= n-1 ports
= 10-1
= 9
Here, n=10(total number of computers)
= n(n-1) / 2
= 10(9) / 2
= 45
→ To accommodate that many links, every device on the network must have n-1 input/output(I/O) ports
n=10(total number of computers)
= n-1 ports
= 10-1
= 9
Correct Answer: C
