Suppose a company hires you as network manager and you have to setup their small office as first task that has 10 computers, 2 printers and 1 scanner. To connect all the computers and peripheral devices as a network, you are required to answer the following questions:
i) Which topology do you think will be feasible in such case? Explain with proper reasoning (1-2 lines). (5)
Ans:
Star topology is feasible in this case, because every node connects to central hub therefore network traffic should be controlled and if one node fails it doesn’t affect others.
ii) If Mesh topology is followed then how many number of links and ports are required? (Calculation is necessary to show) (5)
Ans:
10 computers
2printers
1 scanner
Total 13nodes.
By Formula: {n (n-1)}/2
{13(13-1)}/2
{13(12)}/2
156/2
=78 links
I/O ports
13-1
=12 ports
N= total number of devices.
iii) To which category does the given network belong to? (2)
Ans:
This network belongs to LAN network category.
iv) Which mode of communication (simplex, half duplex, full duplex) is suitable when a computer communicates to a printer for printing? Also give one more example of that mode.
(3Ans: Simplex mode is suitable for printing
Example of simplex mode is: mouse to computer
