Ans 1
In this case the best network topology is tree topology because we have 10 pc ,2 printer and one scanner .
1 As the connected devices are more so by tree topology we can connect more devices at a time
2 As we have to form a network in the office so we have to implement a network that require less cabling this can be achieved by tree topology
3 As pc’s are connected to their respective secondary hub so if any fault occurs it can be deduct easily
Ans 2:
If mesh topology is followed then no link and ports which will be required is given below
Total no connected devices are 13 so we have 13 nodes
No links=n(n-1/2) we have n=13
13(13-1/2)=13(12)/2=156/2=78
No of I/O ports=(n-1)=(13-1)=12
Ans 3
The network category is LAN because all the pc has to be interconnected with in the office
Ans 4
Half duplex the example is television or radio
