a. Determine the requirement for deadlock that is removed by the solution to the problem “Both students are allowed in the course”:
Explanation of Solution
Resource allocation means when the two or more processes cannot progress because of the resources unavailability. The next process suffers from resources unavailability because it is waiting for the resource that is still in use by the previous process.
In the given situation both the students are allowed in the course...
b. Determine the requirement for deadlock that is removed by the solution to the problem “The class size is reduced to nineteen, so neither of the two students is allowed to register for the course”:
Explanation of Solution
Resource allocation means when the two or more processes cannot progress because of the resources unavailability. The next process suffers from resources unavailability because it is waiting for the resource that is still in use by the previous process.
In the given situation the size of the class is reduced...
c. Determine the requirement for deadlock that is removed by the solution to the problem “The competing students are both denied entry to the class and a third student is given the twentieth space”:
Explanation of Solution
Resource allocation means when the two or more processes cannot progress because of the resources unavailability. The next process suffers from resources unavailability because it is waiting for the resource that is still in use by the previous process...
d. Determine the requirement for deadlock that is removed by the solution to the problem “It is decided that the only requirement for entry into the course is the payment of the fee. Thus the student who has paid the fee gets into the course, and entry is denied to the other student”:
Explanation of Solution
Resource allocation means when the two or more processes cannot progress because of the resources unavailability. The next process suffers from resources unavailability because it is waiting for the resource that is still in use by the previous process.
In the given situation the student who paid the fees is preferred for the enrolment, thus the second condition is raised here...
