Answer:
Following are the code in java language
abstract interface PointingDevice // interface PointingDevice,
{
// abstract method getXCoord()
public abstract int getXCoord();
// abstract method getYCoord()
public abstract int getYCoord();
// abstract method attentionRequired()
public abstract boolean attentionRequired();
// abstract method setResolution( )
public abstract double setResolution(double a);
}
Explanation:
In this code we have declared a abstract interface "PointingDevice" which contains the four abstract method getXCoord of type int , getYCoord() of type int , attentionRequired() of type boolean and setResolution() of type double .
These method have only declaration not definition any interface or class which inherit the inteface PointingDevice must define all these four method otherwise it also be abstract .
Answer:(C) Anyone with access to the personal computers could log on to the mainframe.
Explanation:
It is no doubt that log on procedures are cumbersome so what most users do is that they store log on sequences in their computer so that they could use the main frame facilities whenever they access it the second time.
Here we have to identify the associated risk with this approach.
This process could lead to access of the computer system to users and thereby making all the data available in the system vulnerable. So option C is correct.
option (A) is incorrect as the back up option who also be affected when the system is accessible to anyone.
option (B) is incorrect because it has nothing to do anything with training of the personnel.
option (D) is incorrect because it one has nothing to do with the physical system what vulnerable reside is inside the system.
Because an IDLE itself runs in a thread, it is not generally a good idea to test a multithreaded application in that environment. is a true statement.
