The code for the one-writer many readers is fine if we assume that the readers have always priority. The problem is that the readers can starve the writer(s) since they may never all leave the critical region, i.e., there is always at least one reader in the critical region, hence the €˜wrt' semaphore may never be signaled to writers and the writer process does not get access to €˜wrt' semaphore and writes into the critical region.

The code for the one-writer many readers is fine if we assume that the readers have always priority.

In the 2016 presidential election, many polls were made available to readers on a daily basis. Of course, each of these polls reported a margin of error that was associated with the results. What is a margin of error, what does it tell us, and why is the margin of error reported? Is the margin of error truly necessary to calculate? Why or why not?

Many animals are in danger of extinction. One way to see the extent of the problem is to study the numbers of animals on the endangered species list. The following data show the numbers of endangered species for various groups of animals. The count is the total number of endangered species within the group. Thus, there are 37 mammals on the endangered species list within the United States and 249 others in the rest of the world. Group United States...
