Let us consider a point to point network having 9 computers. Answer the following questions with complete calculations.

a)      How many connections/links will be needed in order to connect these computers with each other in this point to point network?
Solution: 
                               =(n^2-n)/2
                               = (81-9)/2
                               =72/2=36
a)       How many new connections/links will be needed in order to add a new machine in this network?
Solution: 
                                N-1=9-1=8
