Answer:

both MAC and IPv4 addresses of the DHCP server

FF-FF-FF-FF-FF-FF and IPv4 address of the DHCP server

FF-FF-FF-FF-FF-FF and 255.255.255.255

MAC address of the DHCP server and 255.255.255.255

Explanation:

When the lease of a dynamically assigned IPv4 address has expired, a workstation will send a DHCPDISCOVER message to start the process of obtaining a valid IP address. Because the workstation does not know the addresses of DHCP servers, it sends the message via broadcast, with destination addresses of FF-FF-FF-FF-FF-FF and 255.255.255.255.

Answer:

FF-FF-FF-FF-FF-FF and 255.255.255.255

Explanation:

At the expiration of the assigned IPV4 address, the work station will send a DHCPDISCOVER message so as to initiate the process of getting an authentic IP address. This is because the workstation cannot identify the DHCP serves address.

The second layer address broadcast FF-FF-FF-FF-FF-FF is adopted on the ethernet frame and is assumed to be broadcasted on all equipment.

255.255.255.255 is the 3rd layer address used to label the exact same host.

In this exercise you will debug the code which has been provided in the starter file. The code is intended to do the following:
abruzzese [7]

Answer:

The corrected code is as follows:

import java.util.Scanner;

public class U2_L4_Activity_Two{

public static void main(String[] args){

Scanner scan = new Scanner(System.in);

String str1 = scan.nextLine();

String str2 = str1;

str1 = str1.toUpperCase();

System.out.println(str1);

System.out.println(str2);

}

}

Explanation:

This corrects the scanner object

Scanner scan = new Scanner(System.in);

This line is correct

String str1 = scan.nextLine();

This copies str1 to str2

String str2 = str1;

This converts str1 to upper case

str1 = str1.toUpperCase();

This prints str1

System.out.println(str1);

This prints str2

System.out.println(str2);

Petra notices that there are a number of issues with a new fiber optic connection whose status appears to be going up and down c
DanielleElmas [232]

Fiber Internet is the wired choice of our present times. It has replaced traditional copper-based facilities.

<h3></h3>

How fiber optics are connected?

  • Fiber to the curb (FTTC) means your fiber connection goes to the nearest pole or utility box—not an actual concrete curb. After that, coaxial cables will send signals from the “curb” to your home. This means your connection is made up of part fiber-optic cables, part copper wires.
  • Twisted pair cabling simply refers to a wiring whereby two conductors that are gotten from a single circuit will be twisted together so that their electromagnetic compatibility can be enhanced.
  • This type of network cable is commonly used to connect office computers to the local network and it is used for Ethernet networks. A circuit is formed from the pair of wires which can be used in the transmission of data.
  • Fiber optic internet is a data connection carried by a cable filled with thin glass or plastic fibers. Data travels through them as beams of light pulsed in a pattern. Fiber optic internet speeds are about 20 times faster than regular cable at 1 Gbps.
