What is the purpose of an ARP response?
Answer:
The ARP protocol will tell you the physical address (mac address) of a node based on it's ip address. So effectively one protocol layer lower.
The purpose of an ARP response is to provide the sender with the MAC (Media Access Control) address of a specific Internet Protocol address within a local network.
Ask about the purpose of an ARP response.
Since ARP is necessary because the software address (IP address) of the host or computer connected to the network needs to be translated to a hardware address (MAC address).
Without ARP, a host would not be able to figure out the hardware address of another host.
Hence, an ARP response allows devices on a local network to discover and map IP addresses to MAC addresses, facilitating effective communication between devices at the data link layer.

Answer:
C
Explanation:
A is binary for 35
B 35 base 10 is 35
C is the answer
If userNum1 is less than 0, put "userNum1 is negative.\n" to output. If userNum2 is greater than 10, assign userNum2 with 0. Else, put "userNum2 is less than or equal to 10.\n".
Answer:
I don't know what language you want this in, but I will do it in c++. Let me know if you want it in another language.
if (userNum1 < 0) {
cout << "userNum1 is negative" << endl;
}
else if (userNum2 > 10 {
userNum2 = 0;
} else {
cout << "userNum2 is less than or equal to 10";
}
The code to check the number using if else statement is coded in source code below.
The code snippet in Python to implement the given conditions:
```python
# Assuming userNum1 and userNum2 are the input variables
if userNum1 < 0:
print("userNum1 is negative.")
if userNum2 > 10:
userNum2 = 0
else:
print("userNum2 is less than or equal to 10.")
```
Explanation:
1. The first `if` statement checks if `userNum1` is less than 0.
If it is, the message "userNum1 is negative." will be printed to the output.
2. The second `if` statement checks if `userNum2` is greater than 10.
If it is, `userNum2` will be assigned the value 0.
3. If the condition in the second `if` statement is not met (i.e., `userNum2` is not greater than 10), the `else` block will be executed, and the message "userNum2 is less than or equal to 10." will be printed to the output.

We need to build a model for a category Y for a binary classification problem (with categories of: 0,1) and having one binary attribute X1 (with possible values of: 0,1 per attribute).
The Naïve Bayes algorithm was chosen for training the classification model.
After the training phase, we got the following results:
p(X1=0|Y=0)=0.35, p(X1=1|Y=0)=0.65
p(X1=0|Y=1)=0.3, p(X1=1|Y=1)=0.7
p(Y=0)=0.5, p(Y=1)=0.5
Which of the following answers is correct?
Select the best answer
Select one:
A.
If the category Y=1, we will classify the example as X1=1
B.
If the value of X1 is 0 we will classify the example as category Y=0
C.
If the value of X1 is 1 we will classify the example as category Y=0
D.
None of the answers is correct, since we're missing the probabilities: p(X1=0), p(X1=1),
Answer:
D. None of the answers is correct, since we're missing the probabilities: p(X1=0), p(X1=1),
Explanation:
To calculate the probability that an example belongs to a particular category, we need to know the prior probability of the category (p(Y=0) or p(Y=1)), the probability of the attribute value given the category (p(X1=0|Y=0) or p(X1=1|Y=1)), and the probability of the attribute value (p(X1=0) or p(X1=1)). We are missing the latter two probabilities, so we cannot calculate the probability that an example belongs to a particular category.

Below functions flatten the nested list of integers (List[List[int]]) into a single list and remove duplicates by leaving only the first occurrences. When the total number of elements is N, choose the one that correctly compares the time complexity with respect to N of each function.
f1 = f3 < f2
f1 = f2 < f3
f3 < f1 = f2
f3 < f1 < f2
f1 = f2 = f3
The time complexities of the functions is (a) f1 = f3 < f2
How to compare the time complexities?The time complexities of the functions are dependent on the loops and conditional statements in the function.
From the given code, we have the following highlights:
Function f1: 2 loops and 1 conditional statementFunction f2: 2 loops and 1 conditional statement in the second loopFunction f3: 2 loops and 1 conditional statementConsidering the function f2
The conditional statement in the second loop implies that the conditional statement would be executed several times as long as the loop is valid.
This means that:
f2 > f1 and f2 > f3
Functions f1 and f3 have equal loops and conditional statement.
This means that
f1 = f3
So, we have:
f2 > f1 = f3
Rewrite as:
f1 = f3 < f2
Hence, the time complexities of the functions is (a) f1 = f3 < f2

For the function below, list 4 ordered pairs for that function.
y = 3x + 1
Answer:
(1, 4)
(2, 7)
(0, 1)
(-1, -2)
Explanation:
to find ordered pairs, we plug in different values for x.
(remember, and "ordered pair" is (x, y)--the first number turns into the second number when put through the function)
usually, it's easiest to plug in smaller numbers, so that it is less complicated to graph
so, here's a few x values:
x = 1
y = 3x + 1
y = 3(1) + 1
y = 3 + 1
y = 4
so, when x = 1, y = 4
we write this as: (1, 4)
x = 2
y = 3x + 1
y = 3(2) + 1
y = 6 + 1
y = 7
so, when x = 2, y = 7
we write this as: (2, 7)
x = 0
y = 3x + 1
y = 3(0) + 1
y = 0 + 1
y = 1
so, when x = 0, y = 1
we write this as: (0, 1)
x = -1
y = 3x + 1
y = 3(-1) + 1
y = -3 + 1
y = -2
so, when x = -1, y = -2
we write this as: (-1, -2)
