Considering the following algorithm, which of the following requirements are satisfied?
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;
…
} }
} }
} }

a) mutual exclusion
b) bounded waiting
c) progress
d) none of the above

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.

i think the answer would be a

the printer can be used in a both wired and wireless network, only one of the connection methods can be used at one time when the wireless setting is enabled, the wired (ethernet) setting is disabled.

but first you need to

`connect the cord to your computer

`open settings app from the start menu

`click devices

`than click add printer or scanner

and than you should be able to do it from there, if not let me know i can you! : )
