Answer:
The switch sends broadcast traffic to all ports like a hub to get the number of ports used and build its MAC address table.
Explanation:
A network switch is a device used in a LAN to connect all available workstations. Unlike a network hub, it is able to send frames from a host or workstation to another using its MAC address table.
An example of a switch is the Cisco 2950 switch. When it is first turned on, it acts as a hub, broadcasting traffic to all its ports. This process is used to create a MAC address table to get the IP address of workstations and the ports they relate to, enabling it to send unicast traffic to a specific port.

what is wrong with the following, exercise 1 1313 unread replies.1313 replies. Specify which instructions do not work according to masm syntax and why. ; var1 and var2 are of size bytes mov eax, var1 mov var1, var2 mov bx, var2 mov bh, var1
Answer:
The solution to this question can be defined as follows:
Explanation:
If we learn, they should use normal intel syntax in MASM assembly language when writing assembly codes. Consequently, its first operand was its venue, and another is the source as per this intellect syntax.
For instance. In mov eax ,var1
eax is a 32-bit data registry that would be the aim, that is copies to eax by the meaning of var1.
bx is a 16-bit base registry that has a var2 value.
bh is indeed a simple registry 8-bit component provided to the Var1 value.
It's not the Master Syntax, because they transfer the data contained from var2 to var1 explicitly instead of using the records. It's the best approach, when they move data, through the registers.

Complete the static method yearsToVote, which returns a String displaying the number of years a person has been able to vote or the number of years they have to wait to vote (the voting age is 18). The age is passed in as an argument.
public static String yearsToVote (int age) {
** Complete the code **
}
Answer:
Following are the code to this question:
public class Main//defining a class
{
public static String yearsToVote(int age)//defining a method yearsToVote that holds an integer variable as a parameter
{
String s;//defining a String variable
int a;//defining a integer variable
if(age<18)//defining if block to check age
{
a=18-age;//calculating the age value
s="The Person has to wait "+a+ " more years before they can vote";//print string value with age
}
else//defining else variable
{
a=age-18;//calculating age value
s="Since last " +a+" years person has been abel to vote ";//print string value with age
}
return s; // return String value
}
public static void main(String[] args)//defining a mein method
{
int age=22;//defining an integer variable with value
System.out.println(yearsToVote(22));//use print method to call static method
}
}
Output:
Since last 4 years person has been abel to vote

In this code, a static method "yearsToVote" is declared that accepts an integer variable "age" in its parameter, and defined one string and one integer variable, and use if block to check value and return string value with a message.
In the next step, the main method is declared, which defines an integer variable and holds its value and passes into the method "yearsToVote" use the print method to call and print its value.
As a security measure, you implement time and date stamps in a payroll application program while transactions are being recorded. What is the role of this security measure
Answer:
Explanation:
The main role of this security measure is to maintain the integrity and validity of the recorded transactions. Implementing these timestamps and dates allows for transactions to be completely organized and easily found by simply searching for the time that the transaction took place. This also helps prevent anyone from making false transactions as they can be easily traced using these time stamps to make sure that they actually happened.

Answer:
The first one, 99.14.242.51 is the only valid IPv4 address listed.
Explanation:
An IPv4 address is formatted as four eight-bit numbers separated by decimals. This means that a valid one will have four numbers from 0 to 255, with decimals in between.
The first one, 99.14.242.51 is a valid IPv4 address.
The second one has the number 342, which is greater than eight bits.
The third one has five octets.
The fourth one is in the wrong format altogether, using what appear to be 32-bit numbers
The __________ operator increases the value of the variable by 1 after the original value is used in the expression in which the variable appears.
Answer:
postincrement.
Explanation:
In Computer programming, a variable can be defined as a placeholder or container for holding a piece of information that can be modified or edited.
Basically, variable stores information which is passed from the location of the method call directly to the method that is called by the program.
For example, they can serve as a model for a function; when used as an input, such as for passing a value to a function and when used as an output, such as for retrieving a value from the same function. Therefore, when you create variables in a function, you can can set the values for their parameters.
The postincrement operator increases the value of the variable by 1 after the original value is used in the expression in which the variable appears.

Write a Python 3 program to read from a .csv file containing rates from power companies. Your program should determine the average commercial rate, and also display the information for the highest and lowest rates found.
Answer:
In python:
file = open("rates.csv", "r")
ratecount = 0
ratesum = 0
mylist = []
rates = file.readlines()
for nums in rates:
num = nums.rstrip('\n')
mylist.append(int(num))
for i in num:
ratesum= ratesum + int(i)
ratecount = ratecount + 1
print("Maximum Rate: "+str(max(mylist)))
print("Minimum Rate: "+str(min(mylist)))
print("Average Rate: "+str(ratesum/ratecount))
Explanation:
This opens the csv file
file = open("rates.csv", "r")
This initializes the number of rates in the file
ratecount = 0
This initializes the sum of the rates
ratesum = 0
This initializes an empty list
mylist = []
This reads the rates into lines
rates = file.readlines()
This iterates through the rates (as a string)
for nums in rates:
This removes the newline character \n in the rates
num = nums.rstrip('\n')
This appends the rates (as an integer) to the empty list
mylist.append(int(num))
The following counts the rates in the file and also sum them up
for i in num:
ratesum= ratesum + int(i)
ratecount = ratecount + 1
This prints the maximum of the rates
print("Maximum Rate: "+str(max(mylist)))
This prints the minimum of the rates
print("Minimum Rate: "+str(min(mylist)))
This calculates and prints the average rate
print("Average Rate: "+str(ratesum/ratecount))

Explanation:
From the program, the range is 0 to 5.
The following line iterates from 0 to 5 using "number" as its iterating variable
for number in range(6):
This prints each number in the range followed by a blank space
print(number, end=' ')
The for loop with a range function that prints the following output 0 1 2 3 4 5 is as follows:
for i in range(6):
print(i)
The code is expected to print the values 0 1 2 3 4 5.
A for loop is used to loop through the range values of 6. The range value of 6
are 0 1 2 3 4 and 5.
The range function is used as required to get the value.
Finally, we print the looped values
The code will output 0 1 2 3 4 5

Aaron is staying at a hotel that charges $100 per night plus tax for a room. A tax of 8% is applied to the room rate per day and an additional one-time fee of $5.00 is charged by the hotel. Which of the following represents total charge, in dollars, for staying x nights?
(100 + .08*x) + 5
1.08(100*x) + 5 correct answer
1.08(100*x + 5)
1.08(100 + 5)* x
Template for your consideration
T = .08 # tax for each day
F = 5.00 # one time fee
R = 100 # room rate
d = int(input("Enter the number of days stayed at the hotel "))
c = 0 # initialize cost variable
if (d > 0): # days > 0

def find_max(nums: [int]) -> int:
'''
Finds the maximum value in the given list of integers,
or None if the list is empty
'''
largest = None
for num in nums:
if largest == None or num > largest:
largest = num
return largest
Rewrite the find_max function so that it uses recursion to work its way through the list instead of using a loop. Your rewritten function should accept the same kinds of inputs (i.e., a one-dimensional list of integers) and generate the same outputs. In your view, is this a problem that's well-suited to a recursive solution in Python.
Answer:
The program in recursion is:
def find_max(nums):
if len(nums) == 0:
return "None"
elif len(nums) == 1:
return nums[0]
else:
return max(nums[0],find_max(nums[1:]))
Explanation:
This line defines the function
def find_max(nums):
This checks if the list is empty.
if len(nums) == 0:
If yes, it returns "None"
return "None"
If the list has just one element
elif len(nums) == 1:
It returns the only element as the maximum
return nums[0]
If the list has numerous elemente
else:
The maximum is determined recursively
return max(nums[0],find_max(nums[1:]))
To the (b) part:
This program does not necessarily need to be done recursively because the max built-in function can be used to determine the maximum of the list in just one line of code and it is more efficient.

You decide to store data in the user's browser in order to reduce the amount of data that must be downloaded. What is this process called
Answer:
client-side storage
Explanation:
The process of doing this is known as client-side storage. Like the name suggests this saves data that is sent to the user's computer on that computer either as cookies or cached data. This data is then used every time that the user decides to enter the same website or access the same program from the browser. Doing this allows these websites and programs to load much faster the more times that the user decides to enter them.
Ethernet ensures that _____ on a shared network never interfere with each other and become unreadable.
Answer:
Signals.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Ethernet ensures that signals on a shared network never interfere with each other and become unreadable through the use of encapsulation and standard encryption protocols.
In Computer Networking, encapsulation can be defined as the process of adding a header to a data unit received by a lower layer protocol from a higher layer protocol during data transmission. This ultimately implies that, the header (segment) of a higher layer protocol such as an application layer, is the data of a lower layer such as a transportation layer in the Transmission Control Protocol and Internet Protocol (TCP/IP).
The TCP/IP model comprises of four (4) layers;
1. Application layer: this is the fourth layer of the TCP/IP model. Here, the data unit is encapsulated into segments and sent to the transport layer.
2. Transport layer (layer 3): it receives the segment and encapsulates it into packets and sends to the internet layer.
3. Internet layer (layer 2): packets are encapsulated into frames.
4. Network layer (layer 1): frames are then converted into bits and sent across the network (LAN).
Hence, the data unit encapsulated inside a packet is known as segment, which is typically referred to as packet segmentation.
Additionally, these data, segments, packets, frames and bits transmitted across various layers are known as protocol data units (PDUs).

Explanation:
Write a Java program that asks the user to enter an array of integers in the main method. The program will ask the user for the number of integer elements to be put in the array, and then ask the user for each element of the array. The program then calls a method named isSorted() that accepts an array of integers and returns true if the list is in sorted (increasing) order and false otherwise. For example, if arrays named arr1 and arr2 store [10, 20, 30, 41, 56] and [2, 5, 3, 12, 10] respectively, the calls isSorted(arr1) and isSorted(arr2) should return true and false respectively. Assume the array has at least one integer element. A one-element array is considered to be sorted.
Answer:
The program is as follows:
import java.util.Scanner;
public class MyClass {
public static Boolean isSorted(int [] arr){
Boolean sorted = true;
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
if(arr[i]>arr[j]){
sorted = false;
break;
}
}
}
return sorted;
}
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
System.out.print("Length of array: ");
n = input.nextInt();
int[] arr = new int[n];
System.out.println("Enter array elements:");
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
Boolean chk = isSorted(arr);
System.out.print(chk);
}
}
Explanation:
The method begins here
This line defines a method named isSorted
public static Boolean isSorted(int [] arr){
This line declares a boolean variable and initializes it to true
Boolean sorted = true;
The next two iterations iterate through elements of the array
for(int i = 0;i<arr.length;i++){
for(int j = i;j<arr.length;j++){
This compares an array element with next elements (to the right)
if(arr[i]>arr[j]){
If the next element is smaller than the previous array element, then the array is not sorted
sorted = false; The boolean variable is updated to false
break; This breaks the loop
}
}
}
This returns true or false, depending on the order of the array
return sorted;
}
The main method begins here
public static void main(String args[]) {
Scanner input = new Scanner(System.in);
int n;
This prompts user for length of array
System.out.print("Length of array: ");
This gets length of array from user
n = input.nextInt();
This declares an array
int[] arr = new int[n];
This prompts user for array elements
System.out.println("Enter array elements:");
The following iteration gets the array elements
for(int i = 0; i<n;i++){
arr[i] = input.nextInt();
}
This calls the isSorted array
Boolean chk = isSorted(arr);
This prints true or false, depending if the array is sorted or not
System.out.print(chk);
}
