Suppose there is a class AirConditioner. The class supports the following behaviors: turning the air conditioner on and off. The

following methods are provided for these behaviors: turn_on and turn_off. Both methods accept no arguments and return no value. There is a reference variable office_a_c of type AirConditioner. Create a new object of type AirConditioner using the office_a_c reference variable. After that, turn the air conditioner on using the reference to the new object.

Answer:

The code is given in the explanation section

Explanation:

//Class Airconditioner

public class AirConditioner {

   private boolean turnOnOff;

//The Constructor

   public AirConditioner(boolean turnOnOff) {

       this.turnOnOff = turnOnOff;

   }

//method turn_on

   public void turn_on(){

       this.turnOnOff = true;

   }

//method turn_off

   public void turn_off( ){

       this.turnOnOff = false;

   }

}

// A new class to test the airconditional class

class AircondionTest{

   public static void main(String[] args) {

//Creating an object of the Aircondional class

       AirConditioner office_a_c = new AirConditioner(false);

//Using the reference varible to call method turn_on      

office_a_c.turn_on();

   }

}

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.

Nesterboy [21]

Answer:

c. both the user and the provider of encrypted data.

Explanation:

In assymetric key encryption, you will need the public key of the sender to decode the information along with your private key to decode the encrypted information. if you don't have any of the keys, you won't be able to read the information. You must have both in order to read the information sent.
