which switching method uses the crc value in a frame?
Cut-Through switching is a switching technique that makes advantage of the CRC (Cyclic Redundancy Check) value in a frame. Using a technique known as cut-through switching.
With a network switch's switching method, traffic is forwarded from one network segment to another. Cut-Through switching, Store-and-Forward switching, and Fragment-Free switching are the three switching techniques most frequently employed in contemporary computer networks. Cut-Through switching is the quickest way, however because there is no error checking before forwarding, there may be more errors sent on. Switching between stores and forwards is longer but offers more complete error detection because the full frame is checked before being forwarded. Fragment-Free switching, a hybrid technique, checks only the first 64 bytes of a frame before forwarding it in an effort to strike a balance between speed and error checking. The right switching technique should be chosen based on the network's speed, dependability, and mistake tolerance.

Please Help! Unit 6: Lesson 1 - Coding Activity 2
Instructions: Hemachandra numbers (more commonly known as Fibonacci numbers) are found by starting with two numbers then finding the next number by adding the previous two numbers together. The most common starting numbers are 0 and 1 giving the numbers 0, 1, 1, 2, 3, 5.
The main method from this class contains code which is intended to fill an array of length 10 with these Hemachandra numbers, then print the value of the number in the array at the index entered by the user. For example if the user inputs 3 then the program should output 2, while if the user inputs 6 then the program should output 8. Debug this code so it works as intended.
The Code Given:
import java. Util. Scanner;
public class U6_L1_Activity_Two{
public static void main(String[] args){
int[h] = new int[10];
0 = h[0];
1 = h[1];
h[2] = h[0] + h[1];
h[3] = h[1] + h[2];
h[4] = h[2] + h[3];
h[5] = h[3] + h[4];
h[6] = h[4] + h[5];
h[7] = h[5] + h[6];
h[8] = h[6] + h[7]
h[9] = h[7] + h[8];
h[10] = h[8] + h[9];
Scanner scan = new Scanner(System. In);
int i = scan. NextInt();
if (i >= 0 && i < 10)
System. Out. Println(h(i));
}
}
The code provided in the question intends to fill an array of length 10 with these Hemachandra numbers, then print the value of the number in the array at the index entered by the user. However, there are several errors in the code that prevent it from working correctly.
Hemachandra numbers, more commonly known as Fibonacci numbers, are a sequence of numbers that are found by starting with two numbers and then finding the next number by adding the previous two numbers together. The most common starting numbers are 0 and 1, giving the numbers 0, 1, 1, 2, 3, 5, and so on. [1]
Firstly, there is a syntax error in the first line of the main method. The code "int[h] = new int[10];" should be "int[] h = new int[10];".
Secondly, the indices of the array are off by one. Arrays in Java are zero-indexed, meaning that the first element is at index 0 and the last element is at index 9. The code tries to access index 10, which is out of bounds and will result in an ArrayIndexOutOfBoundsException. Therefore, the last two lines should be changed to "h[8] = h[6] + h[7];" and "h[9] = h[7] + h[8];".
Finally, there is a syntax error in the last line of the code. The code "System. Out. Println(h(i));" should be "System.out.println(h[i]);".
Here is the corrected code:
import java.util.Scanner;
public class U6_L1_Activity_Two{
public static void main(String[] args){
int[] h = new int[10];
h[0] = 0;
h[1] = 1;
h[2] = h[0] + h[1];
h[3] = h[1] + h[2];
h[4] = h[2] + h[3];
h[5] = h[3] + h[4];
h[6] = h[4] + h[5];
h[7] = h[5] + h[6];
h[8] = h[6] + h[7];
h[9] = h[7] + h[8];
Scanner scan = new Scanner(System.in);
int i = scan.nextInt();
if (i >= 0 && i < 10)
System.out.println(h[i]);
}
}
Now, if the user inputs 3, the program will output 2, while if the user inputs 6, the program will output 8

The method computes the employee's wage, stores it in the wage array, and returns it. The fixed wage is the amount of money each employee is paid per day, and the per item wage is the amount of money each employee is paid per item sold.
To receive full credit, the solution must call the computebonusthreshold appropriately.
public void compute wages(double fixed wage, double peritemwage) {
for (int i = 0; i < wages.length; i++) {
wages[i] = fixedwage + peritemwage * itemssold[i];
if (itemssold[i] >= computebonusthreshold()) {
wages[i] += bonus;
}
}}}
The above code performs the following operations: The wages array is declared in the method's signature, and the values are updated using a loop from 0 to the length of the wages array. The current value of wages is calculated by adding fixed wage to peritem wage times the current value of items sold. The wage of the employee is calculated using this formula. Finally, if the current value of items sold is greater than or equal to the computebonusthreshold, the value of wages is increased by bonus. The method computes the employee's wage, stores it in the wage array, and returns it. The fixed wage is the amount of money each employee is paid per day, and the per item wage is the amount of money each employee is paid per item sold.

Why does it take much less space to store digital information than analog information?Digital devices only record pieces of sound waves, not full waves.Digital devices record sounds at lower volumes than analog devices.Digital devices decrease the amplitudes of sound waves, making them smaller.Digital devices automatically eliminate all background noise from the sounds they record.
Due to the fact that digital devices only capture partial sound waves rather than entire waves, digital information requires far less storage space than analogue information.
All data that is transferred or stored in a binary format, which consists of 0s and 1s, is referred to as digital information. Digital text, photos, music, and video are all included. Digital information has the major benefit of being easily copied, exchanged, and sent across vast distances with little to no quality degradation. Also, it is simple to store and access from digital devices like computers and smartphones. A vital component of contemporary communication, entertainment, and technology, digital information is also very adaptable and may be altered in a variety of ways, such as editing, compression, and encryption.

Say list1 is a MyArrayList and list2 is a MyLinkedList. Each of them has one million double values. Compared to code fragment B, code fragment A is more effective.
What is ArrayList?In the java.util package, there is a class called ArrayList that is a resizable array. Java's built-in arrays and ArrayLists differ in that an array's size cannot be changed; instead, a new array must be created if any elements need to be added or removed. Dynamic arrays, also known as growable arrays, resizable arrays, dynamic tables, mutable arrays, or array lists, are a type of variable-size list data structure that support random access and allow for element addition and removal. Many contemporary, widely used programming languages are included as standard libraries. In contrast to the ArrayList Collection class, which has variable lengths, an array is a data structure with a predetermined length. A key concept in Java is the distinction between an array and an arraylist.To learn more about ArrayList, refer to:

what cisco command display information about the devices connected to routers . information should include device id, local interface, hold time, capability, platform, and port id.
The Cisco command that displays information about the devices connected to routers is the command:
`show cdp neighbors`.
The output of this command provides information that includes device ID, local interface, hold time, capability, platform, and port ID. The Cisco command to display information about the devices connected to routers is `show cdp neighbors`. This command shows you all of the directly attached CDP neighbors. The command lists the neighbouring device's hostname or IP address, interface ID, and platform, as well as the time that the neighbor device has been alive. When you enter the `show cdp neighbors` command, you will get an output of all directly connected routers or switches that have CDP enabled on their interfaces.
Cisco Discovery Protocol (CDP) is a proprietary protocol that Cisco Systems devices use to exchange information about other directly attached Cisco equipment. CDP information is always transmitted as broadcast on the link, allowing neighbors to become aware of one another. CDP can provide useful information to network administrators about other devices that are linked to their network, including the name of the device and its interface ID. CDP may also be used to validate Cisco hardware and software versions on directly connected devices.

you have been provided a code for creating a deck of cards: deck of cards.py. in addition you have been given a few different codes for sorting elements in a list: quick sort.py, bubble sort.py, insert sort.py, and selection sort.py. what you have been tasked to do is: utilize one of the above sorting algorithms to sort the cards in the deck both by suit and by value. the suits should be ordered in the same order in which the deck is created (see line 6 of deck of cards.py) create a property that determines whether or not the deck is sorted. create a search method that allows a user to describe a card and will return the location (array index) of the card. this search can easily be made to be high intelligent what can you do to make this search a constant time look up?
To sort the deck of cards by suit and by value, we can use the quick sort algorithm. Here's an example implementation:
python
class Deck:
def __init__(self):
self.cards = []
self.suits = ['Clubs', 'Diamonds', 'Hearts', 'Spades']
self.values = ['Ace', '2', '3', '4', '5', '6', '7', '8', '9', '10', 'Jack', 'Queen', 'King']
for suit in self.suits:
for value in self.values:
self.cards.append(value + ' of ' + suit)
self.is_sorted = False
self.index_dict = {}
What is the code about?
To make the search method a constant time lookup, we can use a hash table to store the location of each card in the deck. We can create the hash table when the deck is created or sorted, and then use it to look up the location of a card in constant time.
Therefore, To make the search a constant time lookup, we can use a dictionary where the keys are the card descriptions (e.g. "Ace of Spades") and the values are the array indices of the cards in the sorted deck.
