Answer:
total time to read whole file = ( 81.380208 mili seconds ) + 80ms + 80ms
Explanation:
Size of a surface = 675/15 = 45 MB
Size of a track = (Number of sectors per track)*(Size of a sector)
= (144*512)Bytes
= 73.728 KB
Number of tracks where 360KB file is located = 360/73.728 = 4.8828125 (Approx 5 tracks)
So Seek time to go the first track of the file = 80 ms
And after seek time for track to track movement = 4*20 = 80 ms
We need 4.8828125 rotations to read whole file.
Time for 4.8828125 ratations = (60.0/3600.0)*4.8828125 seconds = 0.081380208 seconds = 81.380208 mili seconds
So total time to read whole file = ( 81.380208 mili seconds ) + 80ms + 80ms
Answer:
// program in java.
import java.util.*;
// class definition
class Main
{// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// object to read input
Scanner scr=new Scanner(System.in);
// ask to enter name
System.out.print("Enter Your name: ");
// read name from user
String NAME=scr.nextLine();
// print message
System.out.println("Greetings,"+NAME);
}catch(Exception ex){
return;}
}
}
Explanation:
Read name from user with the help of scanner object and assign it to variable "NAME".Then print a Greetings message as "Greetings,NAME" where NAME will be replaced with user's input name.
Output:
Enter Your name: Rachel
Greetings,Rachel
Answer:
Vendor diversity
Explanation:
Different cybersecurity companies maintain different codebases, which means an exploit that might poke holes in the security of one likely won't breach the other. In this situation, the network would still have an active and effective firewall from one vendor even as the exploit from the other vendor's firewall is being patched.

Try linking an email to your account, if it doesn’t work select forgot your password and you should receive an email where you can re make or change your password to something easier to remember. Are you using the same email account every time, this may also be the reason, if it is the same email they will not allow you to reuse it and it should tell you the email is already in use. Hope this helped
