Question No. 2 [10 Marks]
a) How many connections/links will be needed in order to connect these computers with each other in this point to point network?
Formula to calculate number of connection is (n^2-n)/2
Here number of computer are 9 so (9^2-9)/2 = 36
b) How many new connections/links will be needed in order to add a new machine in this network?
we know that add a new computer require (N-1) new connection. Because we have already 9 computer which need 36 connection, now a new connection it will need.
(N-1)
10-1=9
36+9=45
