⦁ Consider transferring an enormous file of L bytes from Host A to Host B. Assume an MSS of 536 bytes. ⦁ What is the maximum val

timurjin [86]

Answer:

a) There are approximately 2^32 = 4,294,967,296 possible number of the sequence. This number of the sequence does not increase by one with every number of sequences but by byte number of data transferred. Therefore, the MSS size is insignificant. Thus, it can be inferred that the maximum L value is representable by 2^32 ≈ 4.19 Gbytes.

b) ceil(2^32 / 536) = 8,012,999

The segment number is 66 bytes of header joined to every segment to get a cumulative sum of 528,857,934 bytes of header. Therefore, overall number of bytes sent will be 2^32 + 528,857,934 = 4.824 × 10^9 bytes. Thus, we can conclude that the total time taken to send the file will be 249 seconds over a 155~Mbps link.

Virtualization, like cloud computing, is a technology that can be useful for _____ sites. hot warm business cold

natima [27]

Answer: Hot sites

Explanation:

Virtualization in the cloud computing is the technology that are useful for the hot sites. It basically making the virtual image of the network devices so that it can be easily use multiple machine at the similar time.

There are various types of benefits of the virtualization in the cloud computing are as follow:

It protect the system from the system failure.
It is the cost effective technology.
By using this we can easily transfer the data from the physical storage to the virtual server.

A communication between two devices is over the maximum limit of an ethernet frame size. The Transmission Control Protocol (TCP)

umka2103 [35]

Answer:

D. Sequence number

Explanation:

The sequence number facilitates the keeping track of many segments. This enables it to determine which segments out of many in which it should be in. The sequence number field is usually 32 bits.

Sequence numbers are used in transmitting data because of their importance. Since data is transmitted in packets, they can be lost and as such the receiver uses the sequence numbers to reorder them.

4.2: Roman Numeral Converter Write a program that asks the user to enter a number within the range of 1 through 10. Use a switch

Reptile [31]

Answer:

The solution code is written in Java

import java.util.Scanner;
public class Main {
public static void main (String [] args) {
Scanner inStream = new Scanner(System.in);
System.out.print("Please input a number (1 - 10): ");
int num = inStream.nextInt();
if(num < 1 || num > 10){
System.out.println("The input must be between 1 - 10");
}else{
switch(num){
case 1:
System.out.println("I");
break;
case 2:
System.out.println("II");
break;
case 3:
System.out.println("III");
break;
case 4:
System.out.println("IV");
break;
case 5:
System.out.println("V");
break;
case 6:
System.out.println("VI");
break;
case 7:
System.out.println("VII");
break;
case 8:
System.out.println("VIII");
break;
case 9:
System.out.println("IX");
break;
case 10:
System.out.println("X");
break;
}
}
}
}

Explanation:

The first part of this program (Line 6 - 8) is to get input number from user using Scanner object. Input validation has been done to check if the input number is in the acceptable range (Line 10). If not, an error message will be displayed (Line 11).

If the input number is in the range of 1 - 10, the number will go through a series of switch statements checking. If the number meet the condition in one of the switch cases, it will print the corresponding roman numeral specified in the case block (Line 13 - 44). For example, if input number is 9, the case 9 condition is met and "IX" will be printed.
