Answer and Explanation:
Given data:
Distance (D) = 40 KM
Speed of light in the fiber =Distance/ speed of light in the fiber
a) Delay (P) = Distance/ speed of light in the fiber
= (40,000 Meters/2×108 m/s)
=( 40×103 Meters/2×108 m/s)
Propagation delay (P) = 0.0002 seconds or 200 microseconds
b)
if propagation delay is 0.0002 Seconds roundup trip time (RTT) will be 0.0004 Seconds or 400 micro Seconds
Essentially since transmission times and returning ACKs are insignificant all we really need is a value slightly greater than 0.0004 seconds for our timeout value.
c)
The obvious reasons would be if the data frame was lost, or if the ACK was lost. Other possibilities include extremely slow processing on the receive side (late ACK).
Or Extremely Slow Processing of the ACK after it is received back at the send side.
Answer:
modify the NTFS permissions on the folder
Explanation:
In order to solve this problem what you need to do is to modify the NTFS permissions on the folder. The NT File System permissions are security measures blocking access to manipulation of files within a directory and affects local users as well as network users. By adjusting the permissions of this within the folder that the members are trying to access then it will give them the ability to modify the files.
Answer:
The code to this question can be given as:
Code:
int callsReceived,operatorsOnCall; //define variable as integer
Scanner ob= new Scanner(System.in);
//create object of scanner class for user input
System.out.println("Insert the value of callsReceived"); //print message.
callsReceived = ob.nextInt(); //input value.
System.out.println("Insert the value of operatorsOnCall"); //print message.
operatorsOnCall = ob.nextInt(); //input value.
if (operatorsOnCall == 0) //check number
{
System.out.println("INVALID"); //print message.
}
else
{
System.out.println(callsReceived/operatorsOnCall); //print value.
}
Explanation:
In the above code firstly we define 2 integer variable that name is already given in the question. Then we create the scanner class object for taking user input. Then we print the message for input first and second value from the user. then we use conditional statement. If the second variable that is operatorsOnCall is equal to 0. So It print INVALID. else it divide the value and print it.
I don't see any error on your code, everything is well written and simple. Except trying putting PUBLIC on your Class displayer. If you encounter the same problem again try to rebuild your whole code and try to recompile the whole code. Even try restarting your personal computer.
