For the following four scenarios, explain your answer with valid reason.

(i) A cable which was not properly attached with the hub is accidentally pulled out from hub in star topology. Will this network work?

(ii) Due to fluctuation in light, a centralized hub is burnt in star topology. Although all connected devices and cables are unaffected, will these devices be able to access the network?

(iii) A loose terminator gets separated from cable making it open at one end in Bus topology. Will this network work as expected?

(iv) A cable which connects two devices in Ring topology broke. Will remaining devices work normally?
