You are requested to evaluate the following scheduling algorithms and states which could result in starvation? Explain why, by providing a situation that might lead to starvation?
a) First-come, first-served
b) Shortest job first
c) Round robin
Servers are designed to limit the number accepted open connections. For instance, a server may have only N socket connections at any point in time. Once the N connections are established, the server will no longer accept another incoming connection until an existing connection is terminated. Explain how semaphores can be applied by a server to control the number of control on the number of accpeted connections (assuming that the semaphores uses the methods acquire() and release().)
What would the consequences, if the wait() and signal() semaphore operations are not executed atomically, to mutual exclusion. Describe a situation where multiple processes are invoking concurrently the methods wait() (which do not run in atomic fashion);
