Assume Counting Semaphore N=8. On performing 10 down() operations by 10 different processes , first 8 will be successful and last two processes will be suspended. Does this mean that the first 8 processes can enter in the CS at the same time? In other words, does counting semaphore can let multiple processes access the CS at the same time?
