Busy waiting problem
WebYes it still suffers from the busy-waiting problem. Yes it is possible to implement semaphores without busy-waiting. Instead, it just implements block and wake up. Block places the process invoking the operation on the appropriate waiting queue, and then block. Wake up removes one of the processes in the waiting queue and place it in the ready ...

WebAll the synchronization mechanism with busy waiting are also suffering from the priority inversion problem that is there is always a possibility of spin lock whenever there is a process with the higher priority has to wait outside the critical section since the mechanism intends to execute the lower priority process in the critical section. Web2. Both busy waiting and blocking methods can be used as means to address critical section problems and process synchronization. Describe how blocking is different from busy waiting, and discuss the advantages and disadvantages of each. Answer: Busy waiting means a process simply spins (does nothing but continue to test its entry

The process performs busy waiting until the other process has finished it’s own critical section. chanters lodge in livingstone zambiaMost operating systems and threading libraries provide a variety of system calls that will block the process on an event, such as lock acquisition, timer changes, I/O availability or signals. Using such calls generally produces the simplest, most efficient, fair, and race-free result. A single call checks, informs the scheduler of the event it is waiting for, inserts a memory barrier where applicable, and may perform a requested I/O operation before returning.
