1. In the OPT page-replacement algorithm, the reference bits of all the pages in memory have to be reset every clock interrupt.
True or False

Answers

Answer 1

The statement is false because the OPT page-replacement algorithm, the reference bits of all the pages in memory do not have to be reset every clock interrupt.

The OPT algorithm selects the page that will not be used for the longest period of time in the future, based on future memory references. It is not dependent on the current reference bit of the page. Therefore, there is no need to reset the reference bits of all pages in memory.

In fact, the OPT algorithm does not use the reference bits at all. Instead, it requires a prediction of future memory references, which may not be practical in many cases.

This question involves the creation and use of a spinner to generate random numbers in a game. a gamespinner object represents a spinner with a given number of sectors, all equal in size. the gamespinner class supports the following behaviors.

creating a new spinner with a specified number of sectors
spinning a spinner and reporting the result
reporting the length of the current run, the number of consecutive spins that are the same as the most recent spin

write the complete gamespinner class. your implementation must meet all specifications and conform to the example.

Using the knowledge in computational language in JAVA it is possible to write a code that generate random numbers in a game

Writting the code in JAVA:

public class GameSpinner {

int spinner;

int num;

int current;

public GameSpinner(int spinner) {

super();

this.spinner = spinner;

this.current = 0;

this.num = 0;

}

public int spin() {

int curr = 1 + (int) (Math.random() * spinner);

if (this.current == 0 || this.num == 0) {

this.current = 1;

this.num = curr;

return curr;

}

if (this.num == curr) {

this.current = this.current + 1;

return curr;

} else {

this.num = curr;

this.current = 1;

return curr;

}

public int currentRun() {

return this.current;

}
