spayn [35]4 years ago

ARPANET was the network that became the basis for the Internet. Based on a concept first published in 1967, ARPANET was developed under the direction of the U.S. Advanced Research Projects Agency (ARPA). In 1969, the idea became a modest reality with the interconnection of four university computers. The initial purpose was to communicate with and share computer resources among mainly scientific users at the connected institutions. ARPANET took advantage of the new idea of sending information in small units called packets that could be routed on different paths and reconstructed at their destination. The development of the TCP/IP protocols in the 1970s made it possible to expand the size of the network, which now had become a network of networks, in an orderly way.

mips Write a program that asks the user for an integer between 0 and 100 that represents a number of cents. Convert that number
Tanzania [10]

Answer:

Explanation:

The following program was written in Java. It creates a representation of every coin and then asks the user for a number of cents. Finally, it goes dividing and calculating the remainder of the cents with every coin and saving those values into the local variables of the coins. Once that is all calculated it prints out the number of each coin that make up the cents.

import java.util.Scanner;

class changeCentsProgram {

         // Initialize Value of Each Coin

   final static int QUARTERS = 25;

   final static int DIMES = 10;

   final static int NICKELS = 5;

   public static void main (String[] args) {

       int cents, numQuarters,numDimes, numNickels, centsLeft;

       // prompt the user for cents

       Scanner in = new Scanner(System.in);

       System.out.println("Enter total number of cents (positive integer): ");

       cents = in.nextInt();

       System.out.println();

       // calculate total amount of quarter, dimes, nickels, and pennies in the change

       centsLeft = cents;

       numQuarters = cents/QUARTERS;

       centsLeft = centsLeft % QUARTERS;

       numDimes = centsLeft/DIMES;

       centsLeft = centsLeft % DIMES;

       numNickels = centsLeft/NICKELS;

       centsLeft = centsLeft % NICKELS;

       // display final amount of each coin.

       System.out.print("For your total cents of " + cents);

       System.out.println(" you have:");

       System.out.println("Quarters: " + numQuarters);

       System.out.println("Dimes: " + numDimes);

       System.out.println("Nickels: " + numNickels);

       System.out.println("Pennies: " + centsLeft);

       System.out.println();

   }

}

You are capturing packets with a network sniffer and notice a number of packets that are flagged by the sniffer and described as
Rom4ik [11]

Answer:

Transport Layer                                    

Explanation:

  • Transport layer is responsible for correcting data transmission errors which is done by requesting retries also called re-transmission of packets in case of data loss or corrupted data.
  • Transport layer ensures end to end delivery of data making sure that the data is received correctly and in same order in which it was sent.
  • Transmission Control Protocol (TCP) is a protocol in this layer that continues to transmit data packets securely from sender to receiver, identifying packet losses.
  • Transport layer works on packet loss issues and corrects data transmission errors.
  • It has flow control and error control services manage data transmission rate and ensures data is received without error.
  • So in case of transmission errors and re-transmission requests transport layer should be investigated.
