2. A host computer with an IP address of 172.16.29.155 using a subnet mask of 255.255.255.0 and a gateway of 172.16.29.1 pings a

ASHA 777 [7]

Answer:

From the host IP address and subnet mask, you can tell that both computers are on the same network. Host 172.16.29.155 will need to send an ARP request broadcast for 172.16.29.83 to get the MAC address and update its ARP table if the host 172.16.29.83 has not already done so.

Explanation:

<h2>ADDRESS RESOLUTION PROTOCOL (ARP)</h2>

Address Resolution Protocol (ARP) is a procedure for mapping a logical address known as the IP address to a physical address known as MAC (Media Access Control) address in a local area network. The job of the ARP is essentially to translate 32-bit addresses to 48-bit addresses and vice-versa when using IP Version 4 (IPv4) to communicate on the network.

Most of the computer programs/applications use logical address (IP address) to send/receive messages, however, the actual communication happens over the physical address (MAC address) this happens in the layer 2 of the OSI model. An ARP request is a broadcast, and an ARP response is a Unicast.

Scenarios when ARP is used:

Scenario-1: The sender is a host and wants to send a packet to another host on the same network.

· Use ARP to find another host’s physical address

Scenario -2: The sender is a host and wants to send a packet to another host on another network.

· Sender looks at its routing table.

· Find the IP address of the next-hop (router) for this destination.

· Use ARP to find the router’s physical address

Scenario -3: the sender is a router and received a datagram destined for a host on another network.

· Router checks its routing table.

· Find the IP address of the next router.

· Use ARP to find the next router’s physical address.

Scenario -4: The sender is a router that has received a datagram destined for a host in the same network.

· Use ARP to find this host’s physical address.

The situation in the question above falls under scenario-1. From the host IP address and subnet mask, you can tell that both computers are on the same network. Host 172.16.29.155 will need to send an ARP request broadcast for 172.16.29.83 so to get the MAC address and update its ARP table if the host 172.16.29.83 has not already done so.

________ is the process of inspecting data that has been input to a program to make sure it is valid before using it in a comput

Mumz [18]

Answer:

Hence, Input Validation is the process of inspecting data that has been input to a program to make sure it is valid before using it in a computation.

Explanation:

The input should be validated before further processing to avoid problems in execution of program afterwards.

The process of input validation is defined to make sure that the input is valid.

Hence, Input Validation is the process of inspecting data that has been input to a program to make sure it is valid before using it in a computation ..

What is the symbol that causes the computer to perform string concatenation?

neonofarm [45]

Answer: In java the symbol "+" operator is used to perform string concatenation.

Explanation:

String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.

An example of String concatenation is as follows:

int age = 10;

System.out.println("The boys age is " + age);

Output:

The boys age is 10.

here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.

In order to paint a wall that has a number of windows, we want to know its area. Each window has a size of 2 ft by 3 ft. Write a

Eva8 [605]

Using the knowledge in computational language in JAVA it is possible to write a code that write a program that reads the width and height of the wall and the number of windows, using the following prompts

<h3>Writting the code:</h3>

import java.util.Scanner;

public class WallArea {

public static void main(String[] args) {

Scanner sc = new Scanner(System.in);

final int areaOfWindows = 6;

System.out.print("Wall width: ");

double width = sc.nextDouble();

System.out.print("Wall height: ");

double height = sc.nextDouble();

System.out.print("Number of windows: ");

double numberOfWindows = sc.nextDouble();

double area = (width * height) - (numberOfWindows * areaOfWindows);

System.out.println("Area: " + area);

}

}
