Blog: CS601 Assignment Solution Idea 2 Question 02

n = total number of devices
Formula No. of link is
n(n-1)/2
so here
Computer is 6,
Printer is 2,
No. of nodes is 8
n = 8
If we take in mind that
1_Printer as a node
2_and printer can’t connect to each other
then
we connect each computer and printer together same this which u show already…



So,
8(8-1)/2
=28 links
And
I/O Ports = n-1
                  =8-1=7
phir to is mein confussion wali bat nhi...red line just show...different device connect to computer..
 in this case printer used as a node as well as connect to each other..
