Answer:

The best answer is letter D.  

Explanation:

Downloading of files without your permission is a form of security threat and attack. You as unwilling victim will have your files and private information stolen.

One of the basics of internet security is to terminate any connection that you have in a network to stop the possible attack or threat. Worst case scenario is we can shut down our computers or devices or gadgets. But if we can just terminate the connection without performing a force shut down on the device, it is much better. This will give us more time to save what we are working on and to prevent losing important works or data. Terminating the connection from the network comes in various activities such as:  

*Disconnect from the internet - this is one of the most effective method. As most of the attacks are coming from external threats such a hacking.  

*Closing the browser - this could be helpful as well. Hackers are using browser to monitor their victims. And malwares and adwares are most active while we use browsers as they are embedded and using it to propagate to peform their activities.  

*Disconnect from the local network - if you have closed the internet connection and any active software that you are working on presently and the downloading of files still persists, probably the attack comes from your local network. You must close any connection that you have within the local network.

*Deleting the recent files you have downloaded - You must delete any recent files that you just downloaded from your email or from the internet. There might be malware embedded in the file. Malwares are used by hackers to get in to their victims computer without them knowing it.

Then after terminating all the connections, you must call on your Instructor's attention. He / She is the authority in charge and must be aware of the situation.

A file named "games.txt" exists and has 80 lines of data. You open the file with the following line of code.
kirill115 [55]

Answer:

2 lines

Explanation:

The "w" flag will overwrite any content, so the existing 80 lines are lost.

Then, if you write two lines, there are two lines in the file.

You could argue that the final newline character causes a third line to be present, but logically, there are two lines.

Write a program that asks the user to enter the amount s/he has budgeted for a month. The amount should be between 1000 and 2000
Elena-2011 [213]

Answer:

The program to this question can be given as:

Program:

  //import package for user input.

import java.util.*;      

//define class

public class Budget                      

{

public static void main(String [] a)            //define main method.

{

//creating Scanner class object.

Scanner ob =new Scanner(System.in);    

//define variable.      

double budgetamount=0, amountspent=0 ,difference=0,total=0,num=0 ;        

int count = 0;                            

System.out.println("How much have you budgeted for the month? :");        //print message.

budgetamount=ob.nextDouble();                             //taking input

       while(budgetamount != 0)           //checkig number greater then 4 digite.

       {

           budgetamount= budgetamount/10;        

           ++count;

       }

       if(count>4)                 //condition

       {

       System.out.println("enter each expense, then type -999 to quit: ");

       while(num!=-999)               //taking expense  

       {

       total=total+num;                 //totaling expense

       num=scan.nextDouble();                  

       }

       if(total<=budgetamount)           //condtion for over budget.

       {

       System.out.print("under budget:");         //print message

       System.out.print(budgetamount-total);

       }

       else

       {

       System.out.print("over budget:");              //for under budget

       System.out.print(total-budgetamount);

       }

       }

       else

       {

       System.out.println("not valid");        //message for number lessthen 4 digit.    

       }                                      

}

}

output:

How much have you budgeted for the month? : 1200.55.

enter each expense, then type -999 to quit: 365.89

556.90

339.98

-999

over budget:1262.77

Explanation:

The explanation of this program can be given as:

In the above program we import the package in that is used for scanner class. This class is used for the input from the user after input we use the while loop and if-else statement. The while loop is the entry control loop It is used for input validation and if-else is used for the checking condition. Then we insert expense that is inserted by the user. Then we calculate under-budgeted and over-budgeted by conditional statement that is if-else. and at the last we print it.
