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.

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

What is the difference between password protection and encryption? please answer quick, i cant pass this test for the life of me
Answer:Password protection is like locking something in a safe-deposit. It means no one can get to the locked content without knowing the right combination. This method is used on separate documents, folders, and other data the computer's user may want to protect from other people who might have access to the device. The problem is, if someone interested in such content obtains the password or finds a way to open it without it, the content might be revealed despite the owner's efforts to keep it hidden. Unfortunately, there are a lot of ways hackers could obtain the password or hack in without it. For example, it could be obtained with the help of malware, or it might be guessed if the user chooses a weak password. Not to mention, when it comes to PDF documents, the passwords placed on them can be removed using the CMD window or specific.
Password encryption is a step up from password protection. The term can be a tad confusing because, in fact, you cannot encrypt the password itself. Instead, by setting up "password encryption" you are creating a password AND encrypting the contents of the file. In our example (see instructions below), the contents of the user's PDF document are not only password protected, but also encrypted. It is a process during which the content one wishes to keep secret is altered to make it unrecognizable. For example, if it is a text document, letters of each word might be shuffled with additional characters so the words would no longer make any sense. The reverse process is only available if the person who wants to decrypt this data can provide a specific decryption key or a password. In other words, even if the password is removed no one could read the hidden content as it still would need to be decrypted. Of course, it is important to realize you might be unable to retrieve it too if you lose the decryption key, aka, the password.
PLS MARK ME AS BRAINLIEST.
Password protection restricts access to a resource, while encryption secures the actual content of that resource by transforming it into an unreadable form.
Ask about the difference between password protection and encryption.
Now, Password protection and encryption serve different purposes when it comes to securing data.
Password protection is a method of restricting access to a device, system, or specific files by requiring users to enter a password. It acts as a barrier to prevent unauthorized individuals from accessing the protected resource.
The password is typically a combination of characters that only authorized users should know.
Encryption, on the other hand, is a technique used to convert plain text or data into an unreadable format, called ciphertext, using an encryption algorithm.
The ciphertext can only be decrypted back to its original form by someone possessing the decryption key.
Encryption ensures that even if someone gains unauthorized access to the data, they will not be able to read or understand it without the decryption key
Hence, Both measures are commonly used together to enhance data security.

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.
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)

What is an array?An array in terms of computer science is a linear data structure, which stores the same type of data in a compact or contagious way and in adjacent memory locations.
