The correct answer is a. effective communication
- - -
Ineffective and barriers to communication are problems that make communication unclear. Workplace communication is at work or at a job. This is not a job newsletter for workers, but for people at home.
Answer:
int sumid=0; /* Shared var that contains the sum of the process ids currently accessing the file */
int waiting=0; /* Number of process waiting on the semaphore OkToAccess */
semaphore mutex=1; /* Our good old Semaphore variable ;) */
semaphore OKToAccess=0; /* The synchronization semaphore */
get_access(int id)
{
sem_wait(mutex);
while(sumid+id > n) {
waiting++;
sem_signal(mutex);
sem_wait(OKToAccess);
sem_wait(mutex);
}
sumid += id;
sem_signal(mutex);
}
release_access(int id)
{
int i;
sem_wait(mutex);
sumid -= id;
for (i=0; i < waiting;++i) {
sem_signal(OKToAccess);
}
waiting = 0;
sem_signal(mutex);
}
main()
{
get_access(id);
do_stuff();
release_access(id);
}
Some points to note about the solution:
release_access wakes up all waiting processes. It is NOT ok to wake up the first waiting process in this problem --- that process may have too large a value of id. Also, more than one process may be eligible to go in (if those processes have small ids) when one process releases access.
woken up processes try to see if they can get in. If not, they go back to sleep.
waiting is set to 0 in release_access after the for loop. That avoids unnecessary signals from subsequent release_accesses. Those signals would not make the solution wrong, just less efficient as processes will be woken up unnecessarily.

In addition to the obvious temptations in Berkilak's castle with his wife (all of which involve erotic temptation and the temptation to violate hospitality for personal pleasure), more significant spiritual temptations frame this story. First, Gawain displays an element of pride when he agrees to participate in the initial contest. While Arthur is more to blame and Gawain offers to take his place, it certainly is not prudent to participate in this contest with a character whose appearance suggests that he is not a normal, mortal man. The first part of this bargain therefore involves the temptation of pride.

Later, the temptation that most condemns Gawain is the desire to continue living even if one will live a life compromised by deceit. While it is understandable that Gawain would hide the garter and flinch at the blow of an ax, the temptation to focus on his mortal rather than his spiritual life is the cause of his wearing the garter as a mark of shame.
