Answer:
b) Bounded Waiting
Explanation:
int currentThread = 1;
bool thread1Access = true;
bool thread2Access = true;
thread1 { thread2 {
While (true) {
While (true)
{
while(thread2Access == true)
{
while(thread1Access == true)
{
If (currentThread == 2) {
If (currentThread == 1)
{
thread1Access = false; thread2Access = false;
While (currentThread == 2);
While (currentThread == 1);
thread1Access = true; thread2Access = true;
} }
/* start of critical section */ /* start of critical section */
currentThread = 2 currentThread = 1
… ...
/* end of critical section */ /* end of critical section */
thread1Access = false; thread2Access = false;
… ...
} }
} }
} }
It can be seen that in all the instances, both threads are programmed to share same resource at the same time, and hence this is the bounded waiting. For Mutual exclusion, two threads cannot share one resource at one time. They must share simultaneously. Also there should be no deadlock. For Progress each thread should have exclusive access to all the resources. Thus its definitely the not the Progress. And hence its Bounded waiting.
Answer:
The answer is "Option A and Option C".
Explanation:
In choice a, it is true since a client-server design can be used for REST-application. A user is somebody who needs space and it doesn't deal with storing data on a central computer. A client is someone with the money, and the interface does not. Its server doesn't want to worry regarding core functionality on the ends of the server. The server does not have to know anything at all about the layer of UI used at the end of the server.
In choice c, it is true As just a Web app, services like corporate/employee resources must be organized, and HTTP verbs like the GET, Place, POST, DELETE must be used to modify these. It must be obvious, as a programmer, that what is required is clearly to look only at the interface or HTTP method used.
