Your boss asks you to upgrade a desktop computer to add an extra DVI port for a second monitor. How would you recommend completing this request?
Where your boss asks you to upgrade a desktop computer to add an extra DVI port for a second monitor, the following steps are recommended:
If your PC only has one video port, you should be aware that you cannot use a splitter on a single SGVA, HDMI, or DVI interface. If you try to use a splitter with any of these ports, the same image will appear on both displays. It will not expand your work area over both monitors and work independently.
If your PC has a USB port, the best option is to purchase a DisplayLink connector. A DisplayLink connector allows you to connect and extend your display to another display by connecting it to a USB port.
What is a DVI Port?DVI, which stands for Digital Visual Interface, provides a noticeably crisper and better image than VGA. Because it can transport both digital and analog signals, it is a one-of-a-kind connection. DVI may simply be converted to other standards such as HDMI and VGA.
The Digital Display Working Group created the DVI (Digital Visual Interface) digital video interface (DDWG). It is often found on computers, LCD monitors, projectors, and other digital display devices and can accommodate both digital and analog video signals via a single DVI connection.

Python programming using def function
Give the user a math quiz where they have
to subtract 2-digit integers. Present them
like this: 67 - 55.
Each time, tell the user whether they are
correct or incorrect. Continue presenting
problems to them until they enter a zero to
quit. At the end print the number right,
the number wrong, and the percent right.
Explanation:
For this program we'll need to know a couple concepts which are: while loops, user input, variables, converting strings to integers, and basic arithmetic operators, if statements, and the random module.
So let's first just declare the basic function, we can call this "main", or something a bit more descriptive, but for now I'll name it "main".
def main():
# code will go here
main()
so now from here, we want to initialize some variables. We need to somehow keep track of how many they get correct and how many they've answered.
These two numbers may be the same, but at times they will be different from each other, so we'll need two variables. Let's just call the variable tracking how much have been answered as "answered" and the variable tracking how much are correct as "correct".
These two will initially be zero, since the user hasn't answered any questions or gotten any correct. So now we have the following code
def main():
correct = 0
answered = 0
main()
Now let's use a while loop, which we break out of, once the user inputs zero. This may be a bit tricky if we use a condition since we'll have to ask for input before, so let's just use a while True loop, and then use an if statement to break out of it at the end of the loop.
Now we want to generate two numbers so we can use the random module. To access the functions from the random module you use the import statement which will look like this "import random". Now that you have access to these functions, we can use the randint function which generates random numbers between the two parameters you give it (including those end points). It says two digits, so let's use the endpoints 10 and 98, and I'll explain later why I'm limiting it to 98 and not 99.
The reason we want to limit it to 98 and not 99, is because it's possible for the two randomly generated numbers to be equal to each other, so the answer would be zero. This is a problem because the zero is used to quit the program. So what we can do in this case, is add one to one of the numbers, so they're no longer equal, but if they're equal to 99, then now we have a three digit number.
Now onto the user input for simplicitly, let's assume they enter valid input, all we have to do is store that input in a variable and convert it into an integer. We can immediately convert the input into an integer by surrounding the input by the int to convert it.
we of course want to display them the equation, and we can either do this through string concatenation or f-strings, but f-strings are a bit more easier to read.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2:
num2 += 1
userInput = int(input(f"{num1} - {num2}"))
main()
from here we first need to check if they entered zero and if so, break out of the loop. If they didn't enter zero, check if the userInput is equal to the actual answer and if it is, then add one to correct and finally add one to answered regardless of whether their answer is correct or not.
Outside the loop to display how much they got correct we can use an f-string just like we did previously. Since sometimes we'll get a non-terminating decimal, we can use the round function so it rounds to the nearest hundreth.
So let's code this up:
import random
def main():
correct = 0
answered = 0
while True:
num1 = random.randint(10, 98)
num2 = random.randint(10, 98)
if num1 == num2: # the answer would be zero
num2 += 1 # makes sure the answer isn't zero
userInput = int(input(f"{num1} - {num2}"))
if userInput == 0: # first check if they want to stop
break
if userInput == (num1 - num2):
correct += 1
answered += 1
print(f"Correct: {correct}\nIncorrect: {answered - correct}\nPercent: {round(correct/answered, 2)}")
main()
and that should pretty much be it. The last line is just some formatting so it looks a bit better when displaying.
Write an SQL statement to display for every restaurant the name of the restaurant (where the name of the restaurant consists of more than 10 characters) and for every category of menu item its description (catdesc). Furthermore, display the average; cheapest or lowest; and highest or most expensive price of all menu items in that category at that restaurant. Use single row functions to format all the prices. The average price must be padded; the cheapest price must be rounded; but the highest price must not be rounded. Display only those menu items of which the average item price is more than R40. Sort your results according to the restaurant names and for every restaurant from the most expensive average menu item to the cheapest average menu item. Display your results exactly as listed below.

1. Review and write summary report on Artificial Intelligence (AI), your report should include from starting point of Al to the future of AI in brief and short way.
Summary report on Artificial Intelligence (AI):
The term artificial intelligence broadly refers to the application of technology to perform tasks that resemble human cognitive functioning, and is typically defined as "the ability of a machine to imitate intelligent human behaviour." Artificial intelligence typically involves "the theory and development of artificial intelligence systems capable of performing tasks that normally require human intelligence, such as visual perception, speech recognition, decision making, and between languages." John McCarthy, one of the founders of the study of artificial intelligence, "defined the field of using computers to do things that are said to be intelligent when people do them."
Artificial intelligence is used as an umbrella term to cover a wide range of different technologies and applications, some of which are mentioned below.
Machine Learning (ML) Natural Language Processing (NLP) Computer vision (CV) Robotics Process Automation (RPA)AI applications typically involve the use of data, algorithms and human feedback. Ensuring that all these components are properly structured and validated is essential to developing and deploying AI applications.
What is Machine Learning ?Machine learning is a branch of computer science that uses algorithms to process and learn from large amounts of data. Unlike traditional rule-based programming, ML models10 learn from input data to predict or identify meaningful patterns without being specifically programmed to do so. There are different types of ML models depending on their intended task and structure:
Supervised Machine Learning: In supervised ML, a model is trained with labeled input data that correlates with a specified output. Reinforcement learning: In reinforcement learning, the model learns. dynamically to achieve the desired output through trial and error Unsupervised Machine Learning: In unsupervised ML, the input data is unlabelled and the output is undefined Deep Learning: A deep learning model is built on an artificial neural network where algorithms process large amounts of unlabelled or unstructured data through multiple learning layers in a way inspired by how neural networks work in the brainTo learn more about machine learning, visit;

How many subnets and host per subnet are available from network 192.168.43.0 255.255.255.224?
It should be noted that the number of subnets and hosts available from network 192.168.43.0 255.255.255.224 is 8 and 32, respectively. Only 30 of the 32 hosts are generally functional.
What is a host in computer networking?A network host is a computer or other device that is connected to a computer network. A host can serve as a server, supplying network users and other hosts with information resources, services, and applications. Each host is given at least one network address.
A computer network is a group of computers that share resources on or provided by network nodes. To communicate with one another, computers use common communication protocols over digital links.
So, in respect to the above response, bear in mind that we may compute the total number of: by putting the information into an online IPv4 subnet calculator.
8 subnets; and30 hosts available for 192.168.43.0 (IP Address) and 255.255.255.224 (Subnet)

Discuss types of indentation
First,
- select a classification methodology to learn in your project. Select either Classification Trees or Support Vector Machines.
- To actually get the data used in the ISLR examples, you will likely need to download an R package called ISLR; it contains the data sets used in the text.
- Begin by introducing your reader to the corporation from which your stock data (Leggett & Platt Incorporated) comes. Tell the reader something you learned about that corporation that you found interesting, something which would demonstrate to a recruiter that you possess curiosity and the ability to employ it.
- Then, using trimmed screenshots where needed from Excel, sketch out for the reader how you converted your Yahoo-sourced stock data into lagged stock risk data set since 2006.
Second,
-draw a random sample of size n=300 without replacement from your stock return data set. Recall that your stock return data contains a HiLo return column and standardized log lag1 and log lag2 return columns. I will call this your n=300 stock return data set. Show and explain how this is done.
- draw another random sample of size 300 without replacement from your stock return data set. Recall that your stock risk data contains a HiLo risk column and standardized log lag1 and log lag2 columns. I will call this your n=300 stock risk data set.
Next, using your n=300 stock return data set, walk through the steps covered by the ISLR text for your chosen method, SVM or CART, explaining in your own words what you are doing. Put your name into the title of any graphs you show.
Finally, run the program on your n=300 stock risk data set and compare the performance to that of your n=300 stock return data set. Include use of the chi-square test. Discuss the differences, the reasons that these would happen, and the lessons learned about the nature of the stock market.
third,
Select one of the tuning parameters or decision criteria that lie beneath the surface of your chosen methodology, CART or CART. Engage with it by researching beyond the ISLR text. Then experiment with it. Experiment with your data and with other data sets. Try decreasing or increasing n. Look at other sources for help, documenting the sources.
Forth,
Create classification space plots for both of your n=300 data sets, using your chosen methodology, SVM or CART. Be sure to explain how you went about this. Create the plot using the same techniques that we did in our plots for other methods.
] Prepare a comparative study of knn, naive Bayes, logistic regression, and your selected method. Make this comparison on your two n=300 data sets, splitting the data randomly in half to get the training and testing sets.
Explain what you are doing as you go along, explain what you understand about what distinguishes the methods, discuss reasons why the results vary, and why there might be systematic differences in performance between return data and risk data. Show classification space plots for knn, naïve Bayes, and logistic regression. At the end, show a single table in which you summarize the overall correct forecast rate for the stock returns for the four methods; then another table summarizing the performance on the stock risk data
Using the knowledge of the computational language in python it is possible to write a code that Create classification space plots for both of your n=300 data sets, using your chosen methodology, SVM or CART.
Writting the code:def randomize(X, Y):
permutation = np.random.permutation(Y.shape[0])
X2 = X[permutation,:]
Y2 = Y[permutation]
return X2, Y2
X2, y2 = randomize(X, y)
def draw_learning_curves(X, y, estimator, num_trainings):
train_sizes, train_scores, test_scores = learning_curve(estimator, X2, y2, cv=None, n_jobs=1, train_sizes=np.linspace(0.1, 1.0, num_trainings))

What is the vibrating or buzzing of a hand controller known as?
The vibrating or buzzing of a hand controller is known as haptic feedback.
What is haptic feedback?
The use of touch to communicate with users is known as haptic feedback. Most people are familiar with the sensation of a vibration in a phone or the rumble in a game controller, but haptic feedback is much more.
Humans have five senses, but electronic devices communicate with us primarily through two: sight and hearing.
Haptic feedback (also known as simply haptics) alters this by simulating the sense of touch. You can not only touch a computer or other device, but the computer can also touch you.
