Best answer 13 13 votes We can see the example of bridge crossing, in which bridge has only one lane. Deadlock will occur when 2 cars of opposing direction meet. one or more cars may have to backed up if deadlock occurs. Then starvation(indefinite waiting) is possible. ayushigupta answered Oct 5, 2015 • selected Jun 20, 2016 by Desert_Warrior ayushigupta comment Share Follow See all 4 Comments 4 4 Comments reply Tendua commented Oct 5, 2015 reply Follow flag why not system throughput. it will also get affected 6 6 replyShare Arjun commented Jun 20, 2016 reply Follow flag Yes, it does.

5 5 votes I guess starvation should be the answer if we rollback the process there may be possiblity again deadlock occur so it may goes in starvation. OPTION A Umang Raman answered Oct 5, 2015 Umang Raman comment Share Follow 0 reply Please log in or register to add a comment.
1 1 vote 1. Starvation might happen for the process but can be avoided. 2. System throughput will be affected as the whole execution of the process till the rollback is going waste. 3. Device is used in rollback - actually more than the ideal case. 4 Cycle stealing is not a related concept. So, answer is 2- System throughput as starvation might not always be there.

Because all the computation done so far has to done again . This is the reason why you said B ? Computaion matter more rather than no of process queue for starvation and low device utilization 0 0 replyShare Arjun commented Oct 10, 2015 reply Follow flag yes. but it is not just the better option. And you should read the words in question clearly for GATE- starvation "might" happen. But we can't say starvation "will" happen. But "system throughput" will be affected. 0 0 replyShare Sanjay Sharma commented Aug 29, 2018 reply Follow flag here https://gateoverflow.in/18583/isro2009-77 ans is A so which one is correct also system throughput might increase if deadlock is resolved 0 0 replyShare Please log in or register to add a comment.
