Explanation:
Training a model using labeled data and using this model to predict the labels for new data is known as ____________.
Answer:
supervised learning
Explanation:
This process is known as supervised learning. This refers to the machine learning task of learning a function that maps an input to an output based on example input-output pairs. In other words, by teaching it a single process it is able to repeat and predict the same process or predict the output based on the inputs that are being implemented by referring to the initially learned function.
Which part(s) of CAIN is realized through the use of message digest functions and hashes?
Answer:
Integrity
Explanation:
In CAIN, integrity is realized through the use of message digest functions and hashes.
Integrity in CAIN simply means securing a message on transit without it being tampered. To accomplish and achieve integrity, hash functions are used. These hash functions receive arbitrary length message and bring out a fixed sized message digest.
The message digest and hash function maps input data of arbitrary length to an output fixed data length. Hashing is used to guarantee integrity.

when will you need to use a tuple data structure rather than a list of data structure
Answer:
They can always be easily promoted to named tuples. Likewise, if the collection is going to be iterated over, I prefer a list. If it's just a container to hold multiple objects as one, I prefer a tuple. The first thing you need to decide is whether the data structure needs to be mutable or not

5.During a recent network attack, a hacker used rainbow tables to guess network passwords. Which type of attack occurred
Answer:
Rainbow table attack
Explanation:
A rainbow table attack is a type of network attack or hacking where the hacker tries to utilize a rainbow hash table to crack the passwords in a database system. A rainbow table itself is a hash function used in cryptography for saving important data in a database. Especially passwords.
In this process, sensitive data are hashed two or multiple times with the same key or with different keys so as to avoid rainbow table attack. In a rainbow table attack, the hacker simply compares the hash of the original password against hashes stored in the rainbow table and when they find a match, they then identify the password used to create the hash.
Write a second constructor as indicated. Sample output:User1: Minutes: 0, Messages: 0User2: Minutes: 1000, Messages: 5000// ===== Code from file PhonePlan.java =====public class PhonePlan { private int freeMinutes; private int freeMessages; public PhonePlan() { freeMinutes = 0; freeMessages = 0; } // FIXME: Create a second constructor with numMinutes and numMessages parameters. /* Your solution goes here */ public void print() { System.out.println("Minutes: " + freeMinutes + ", Messages: " + freeMessages); return; }}// ===== end =====// ===== Code from file CallPhonePlan.java =====public class CallPhonePlan { public static void main (String [] args) { PhonePlan user1Plan = new PhonePlan(); // Calls default constructor PhonePlan user2Plan = new PhonePlan(1000, 5000); // Calls newly-created constructor System.out.print("User1: "); user1Plan.print(); System.out.print("User2: "); user2Plan.print(); return; }}// ===== end =====
Answer:
public PhonePlan(int numMinutes, int numMessages) {
freeMinutes = numMinutes;
freeMessages = numMessages;
}
Explanation:
Create a constructor that takes two parameters, numMinutes and numMessages
Inside the constructor, set numMinutes to freeMinutes and numMessages to freeMessages.
With this constructor, we are able to create PhonePlan objects that take parameters and different options as seen in the output. We can set any values for minutes and messages in the constructor.
Answer:
PhonePlan::PhonePlan(int numMinutes, int numMessages) {
freeMinutes = numMinutes;
freeMessages = numMessages;
}
Explanation: For C++
PhonePlan::PhonePlan(int numMinutes, int numMessages) {
^^^^^^^^^^^^
you need that
freeMinutes = numMinutes;
freeMessages = numMessages;
}
Which of the following are true statements about collisions in hashing? Linear probing can cause secondary collisions. Higher space utilization tends to cause more collisions.
Answer:
hello the options to your question is incomplete below are the options
A. Linear probing causes secondary collisions.
B. Higher space utilization tends to cause more collisions.
C. Chained entries will be ordered by key.
D. (a) and (b).
E. All of the above.
answer : (a) and (b) --- D
Explanation:
The true statements about collisions in hashing are ;Linear probing causes secondary collisions and Higher space utilization tends to cause more collisions.
collisions in hashing is when two data sets whom are distinctively different have the same hash value or checksum. the collision in hashing can be resolved by checking the hash table for an open slot to keep the data set that caused the collision.
Assume that the variables v, w, x, y, and z are stored in memory locations 200, 201, 202, 203, and 204, respectively.
Using any of the machine language instructions in
Section 5.2.4, translate the following algorithmic operations into their machine language equivalents.
a. Set v to the value of x – y + z. (Assume the existence of the machine language command SUBTRACT X, Y, Z that computes CON(Z) = CON(X) – CON(Y).)
b. Set v to the value (w + x ) - ( y + z)
c. If (v ≥?w) then
set x to y Else set x to z
d. While y < z do
Set y to the value ( y + w + z)
Set z to the value (z + v)
End of the loop
Answer and Explanation:
A. To translate the above algorithm to machine language, we first assign have to perform the first part of the operation which is x-y and set the value to the v variable. The x, y and v values are stored in memory location 202, 203 and 200 respectively.
The z value in the memory location 204 is then added to the v value in memory location 200. The first code sequence is stored in memory location 50 and the second code sequence to achieve x+y-z stored in v is stored in memory location 51(as asummed in question)
B. In the second algorithm, we add value in w which is in memory location 201 to value in x in memory location 202 and assign the result to v in memory location 200. The same is done for y+z in memory locations 203 and 204 respectively with result stored in w. We then subtract the values in v in memory location 200 from w and assign the value to v in memory location 200
C. in the first memory location 50, the code sequence v compared to w is stored. If v(stored in memory location 201)is greater than or equal to w(in memory location 202), it moves to address 54 and assigns the y value to x in memory locations 203 and 202 respectively else it assigns z valuein memory 204 to x value in 202 and jumps to next instruction
D. In this algorithm, it first compares y and z in memory locations 203 and 204 respectively in the first code sequence memory 50. In 51, it checks to see if the condition is satisfied and if it is, it jumps to address 53 and adds y and w in their various memory locations and stores it in memory 203 in y otherwise it moves to address 57. Now to get y+w+z, It then adds y +w in memory location 203 in y to z in memory location 204 and then stores the result in y. Subsequently it adds the z value to v and stores the result in v and moves to address 50 where it compares a new set of value as in a loop in the algorithm which continues till the "while" condition can no longer be satisfied.

The 6 steps for PowerPoint competency from the TED talk in the module "How to Avoid Death by PowerPoint."?
Answer:
1. Do some presentation preparation work
2. Set the right tone and end on a high note.
3. Create sleek and stylish slides.
4. Get your audience to focus.
5. Its all about you.
Explanation:
1. Do some presentation preparation work:
A good presentation begins, not with slides, but with a pencil and paper. Research your audience’s background, interests and capabilities. What do they already know, for instance, and what can they learn from you?
2. Set the right tone and end on a high note:
You have no more than 30 seconds to secure your audience’s attention. So, what attention-grabbing opener will you use?
Visual communications expert Curtis Newbold suggests “a fascinating quote; an alarming or surprising statistic; asking your audience a question; telling a relevant and funny joke… an imaginary scenario; or a demonstration''.
3. Create sleek and stylish slides:
Once you have your story down, you can start to design your slides.
Before you do, it’s important to think about the practicalities. Will they, for instance, be displayed Widescreen with a 16:9 ratio? Or Standard with 4:3? This might seem like a small detail, but it can make a huge difference in terms of visual impact.
4. Get your audience to focus:
The most important thing is to grab your audience’s attention straight away – and then maintain it! You want your audience to go away having learned something. So, make it as easy as possible for people to grasp your message “from the off”!
5. Its all about you:
Finally, remember that, ultimately, it’s you that the audience should be paying attention to, not your slides!
PowerPoint can be used to create great visual aids, but the success of your presentation is determined by the way you deliver them. So, tell your story with a confident, compelling physical presence, and master it by rehearsing it 10 to 15 times.
Code written by computer programmers is translated to binary code, so computers can understand the instructions. True or False
Answer:
True
Explanation:
High-level languages such as Java, C++, Ruby, Python, etc need to be translated into binary code so a computer can understand it, compile and execute them.
Machine language is the only language that is directly understood by the computer because it is written in binary code. But writing codes in Machine Language is tiring, tedious, and obsolete as no one really uses it anymore.

which statement compares the copy and cut commands?
1. only the copy command requires the highlighting text
2. only to cut command removes the text from the original document
3. only the cut command uses the paste command to complete the task
4. only the copy command is used to add text from a document to a new document
Answer:
only to cut command removes the text from the original document
Explanation:
To say that only the cut command removes the text from the original document implies that you can use the cut command on a text, let's say "a boy and girl" to remove the text on the original document where it was located to a new document or text box, in other words, the text "a boy and girl" would no longer be found in the original document.
However, the copy command would not remove the text from the original document.
Answer:
only the command removes the text from the original document.
Explanation:
just did it
4. Write a script called lineCounter that accepts a filename as a command line argument. It should run through the file line by line, displaying a character count for each line. The script should include a line counter, which records the line number, and is incremented when each line is processed.
Answer:
from sys import argv
script, filename = argv
with open( filename ) as file:
line_counter = 0
while True:
extract_line = file.readlines( )
line_counter += 1
character_count = extract_line.count( )
print( " line number: { } , character count: { }". format( line_counter, character_counter )
print ( " Nothing left to count" )
file.close( )
Explanation:
The 'argv' is a module in the python system package, which allows for user input and script execution in the command. It loads the script and the file as a tuple which is offloaded in the script like arguments in a function.
Packet ________ is a form of protection for your computer that looks at each packet that comes into your computer network. screening scanning examination viewing
Answer:
screening
Explanation:
Packet screening also known as packet filtering wall is a package that works at the network layer of the OSI model. It screens IP addresses and packet options and its firewall option allows it to block or allow access into the computer, based on what it has detected.
To achieve this, it can employ the dynamic-packet filtering where ports are opened when it is really necessary and then closed. Static-packet filtering in which rules are set manually and the stateful-paket filtering where packets have to move through some sequence.

Consider two decision problems X and Y. If X reduces in polynomial time to 3-SAT and 3-SAT reduces in polynomial time to Y. Which of the following can be inferred from the previous statement?
a. X is in NP and Y is in NP-Hard.
b. Y is in NP and X is in NP-Hard.
c. Both X and Y are in NP-hard.
d. Both X and Y are in NP.
Answer:
X is in NP and Y is in NP-HARD ( A )
Explanation:
X is in NP and Y is in NP-HARD can be inferred from the previous statement made in the problem above because problem decision X can be in NP if it can BE reducible to a 3-SAT polynomial real time, if that can be achieved then 3SAT will be in NP since SAT is in NP as well.
also problem decision Y can be in NP-HARD if 3SAT can be reducible to it in polynomial time as well hence option A is the correct option

How does enforce password history and minimum password age work together to keep a network environment secure?
Answer:
The Enforce Password History and Minimum Password Age works together by preventing a person from changing the password many times and using an old password.
Explanation:
Minimum Password Age works to stop a user from modifying an existing password numerous times so that it will bypass enforce password history and asked to reset the password.
The Enforce Password History policy works to prevent a user from making use of an old password by setting limits on the number of remembered passwords. This helps users from using old and easily guessed passwords which can leave them vulnerable to network attacks.
