greeting to ganesh sir
i like d website and it helps in competitive exam.sir i hve doubt in question 1 ,i suppose “the function of OS is not:” the ans shud be processor management.
Process management is an integral part of an Operating System. The OS must allocate resources to processes, enable processes to share and exchange information and enable synchronization among processes. So, process management is the function of OS.
great set of questions sir…keep posting…and thanks a lot!!!:)
your answer of 4-2 is wrong bankers algorithm is not used for deadlock prevention it is deadlock avoidance method…
it is nice thank you
the answer for number was to be A…
by the way nice selected questions…love them????
Good job
