Use semaphores to solve the barrier problem where 6 processes execute the same code shown below. No process should be able to execute the statement "critical point" until all processes have executed the statement "rendezvous". (Hint: define semaphore mutex, semaphore barrier and a variable count). Process rendezvous critical point

A parent process calls fork creating a child and continues running but does not call wait. The child calls fork itself and immediately exits (without calling wait), while it's child (the grandchild of the first process) continues running. At this point which of the following correctly describes the situation. The child and the grandchild both become orphans. The child becomes and orphan and the grandchild becomes a zombie. The child becomes a zombie and the grandchild becomes an orphan. The child and the grandchild both become zombies.

These two methods may cancel processes and break deadlocks:

IS THE MECHANISM THAT ENSURES THAT ONLY ONE PROCESS IS DOING CERTAIN EXECUTION AT ONE TIME. Select one: a.MUTUAL EXCLUSION b.COMPETING PROCESSES c.RACE CONDITION d.CRITICAL SECTION

In this project you are to design a process queue that is responsible for handling the process requests coming from different users. You have to take into consideration that users have different levels of privileges and priorities. Each user has an identification number and a password, in addition to process priorities. One good idea is to design the queue using an array or pointers while preserving the first-in first-out concept of the queue. For every process request received, the program should check the privileges of that request and whether it can be moved forward in the queue to be served by the operating system prior to serving the other requests. Using the programming language of your choice (preferably C+), write the process queue that would handle the user request. The program must allow for requests coming from different users or from one user.

Is it possible for a single process to get stuck in a deadlock? Your responses must be justified.

In this question you will be considering the development of a platform through which people working from home can monitor and control machines such as 3D printers, working in a factory. i. You are provided with the following requirement. "User can select a 3D model file from a list and add it to a queue for one of the printers." Write out a step-by-step process that a tester can use to test this requirement. ii. Write TWO requirements for the monitoring part of the platform, using the EARS syntax.

It is possible to have a deadlock involving only a single process. Group of answer choices True False

There are two methods for aborting processes and breaking deadlocks:
