Explanation:

So I'll go through each statement and explain why or why not they're correct.

An object of the ActivationLayer class has a name attribute. So because ActivationLayer is inheriting the BaseLayer and it's calling super().__int__("Activation") it's going to call the BaseLayer.__init__ thus setting a name attribute equal to "Activation" for any ActivationLayer object that is initalized. So this is true

An object of the BaseLayer class has a size attribute. While it is true that FC layer is inheriting from BaseLayer and it has a size attribute, this does nothing to change the BaseLayer class. So any object initialized to a BaseLayer object will only have the instance attribute "self.name". So this is false

print(FCLayer(42)) prints FullyConnectedLayer. So whenever you print an object, it tries to convert the object to a string using the __str__ magic method, but if that wasn't defined it then tries the __repr__ method, which the FCLayer class technically doesn't define, but it inherits it from the BaseLayer class. And since whenever you define an FCLayer object it calls super().__init__ with "FullyConnected", which will then be assigned to the instance variable self.name,  it will print "FullyConnectedLayer". So this is true

When creating an object of the ActivationLayer class, the size argument must be given. This is true, because the size is a parameter of the __init__ method of ActivationLayer, it is not an optional parameter, and is something that must be passed otherwise an error will be raised. So this is false

When creating an object of the BaseLayer class, the name argument must be given. This is not true, because name is a default argument. This means if you do not pass an argument for name, then name will equal an empty string

The line of code that imports the csv file is df = DataFrame(CSV.File("data.csv"))

From the question, the file name is:

data.csv

The syntax that imports the file as a julia dataframe is:

df = DataFrame(CSV.File("file-name"))

Since the filename is data.csv, the code becomes

df = DataFrame(CSV.File("data.csv"))

Hence, the line of code that imports the csv file is df = DataFrame(CSV.File("data.csv"))

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.

The time complexities of the functions is (a) f1 = f3 < f2

The code of the functions f1, f2 and f3 are added as an attachment

To compare the time complexities of the functions, we check the loop and conditional statement in each function.

From the attached code, we can see that:

In function f2, we have:

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 implies that:

f2 > f1 and f2 > f3

The number of loops and conditional statement in functions f1 and f3 are equal

This means that

f1 = f3

So, we have:

f2 > f1 = f3

Rewrite f2 > f1 = f3 as:

f1 = f3 < f2
