Consider a process with a single CPU burst of 100 time units and a single disk I/O of 1000 time units at the end. If the timer interval is fifteen time units and the process scheduling algorithm is round-robin, at most how many times would ... entering the terminated state? Assume that there is a sufficiently large number of processes of similar nature trying to run on the CPU._________

Self Doubt about Dirty Read and Recoverable
I can't exactly identify when a transaction has dirty read problem and when it doesn't. Take the following instances 1. S:T2r(x);T3r(x);T3 commit;T2 commit This is not dirty read as there is no write operation performed by ... this is recoverable. This is what I think regarding the above schedules. Is this right or is it only "JUGAAD"?
