The outputs are in the form of low-level block-read (bread) or block-write (bwrite) commands, which read directly from or write directly to a specific disk and block.Your task is to determine what type of RAID the system is by observing the high-level read/write operations and as well as their underlying block reads/writes to one or more disks.Consider that there are 4 disks in each RAID system.What type of RAID is this?read(0) -> [ bread(disk=0, block=0) ]a)RAID-0 (striping)b)RAID-1 (mirroring)c)RAID-4 (parity)d)All are possibleIt is possible for one process to only execute sem_wait() on a semaphore and for another process to only execute sem_post() on the same semaphore. (Here “only” refers to “only sem_post() without sem_wait()” or vice-versa).choicesTrueFalseIt is possible in a single-processor system to not only interleave the execution of multiple processes but also to overlap their execution on the CPU.TrueFalse Starvation is the situation in which a runnable process is overlooked indefinitely by the scheduler, although it can proceed.Group of answer choicesTrueFalseWill upvoteno wrong answers, please!!Engineering & Technology Computer Science
