Knowledge base.

Explanation:

Artificial intelligence (AI) also known as machine learning can be defined as a branch of computer science which typically involves the process of using algorithms to build a smart computer-controlled robot or machine that is capable of performing tasks that are exclusively designed to be performed by humans or with human intelligence.

Artificial intelligence (AI) provides smarter results and performs related tasks excellently when compared with applications that are built using conventional programming.

Generally, there are two (2) main characteristics of artificial intelligence (AI) systems and these include;

I. Non-algorithmic processing.

II. Symbolic processing.

In artificial intelligence (AI), the field of expert systems is the most important applied area because it models human knowledge.

Hence, expert systems represents knowledge as a set of rules by mimicking the expertise of humans in a particular field to uniquely proffer solutions to a problem.

Although, all expert systems are generally lacking in human capabilities and can only use inference procedures to proffer solutions to specific problems that would normally require human expertise or competence.

Some of the areas where expert systems can be applied are; monitoring, diagnosis, scheduling, classification, design, process control, planning, etc.

Basically, expert systems comprises five (5) main components and these are;

1. Explanation module.

2. Inference Engine.

3. Knowledge acquisition and learning module.

4. User Interface.

5. Knowledge Base.

In the context of the components that makes up an expert system, knowledge base is similar to a database because it is used for storing facts and figures, while keeping track of rules and explanations associated with facts. Thus, giving rise to the knowledge base management system (KBMS).

In the context of the components of a typical expert system, Knowledge base is similar to a database, but in addition to storing facts and figures, it keeps track of rules and explanations associated with facts.

An expert system is a form of artificial intelligence where computer imitate the decision making style of humans.

There are basically two types of the expert system and they are the inference engine and the knowledge base.

The knowledge base consists of the facts and rules and ways of interpreting them to arise to new insights. The inference engine applies logical rules to the knowledge base.

Answer:

c. Copy the executable file to the user’s computer

Explanation:

When you run a c++ program, an executable file (.exe) is created in the same directory with the source file.

To deploy this program on another system, you need to transfer the executable file from the original system where the program was executed to the new system.

The program will work fine without errors.

However, do not mistake the executable file for the source file. The source file ends in .cpp.

Answer:

The program in Python is as follows:

current_price = int(input("Current Price: "))

last_price = int(input("Last Month Price: "))

change = current_price - last_price

mortgage = (current_price * 0.051) / 12

print('Change: {:.2f} '.format(change))

print('Mortgage: {:.2f}'.format(mortgage))

Explanation:

This gets input for current price

current_price = int(input("Current Price: "))

This gets input for last month price

last_price = int(input("Last Month Price: "))

This calculates the price change

change = current_price - last_price

This calculates the mortgage

mortgage = (current_price * 0.051) / 12

This prints the calculated change

print('Change: {:.2f} '.format(change))

This prints the calculated monthly mortgage

print('Mortgage: {:.2f}'.format(mortgage))

Answer:

current_price = int(input())

last_months_price = int(input())

change = current_price - last_months_price

mortgage = current_price * 0.051 / 12

print('This house is $', end= '')

print(current_price, end= '. ')

print('The change is $', end= '')

print(change, end= ' ')

print('since last month.')

print('The estimated monthly mortgage is $', end= '')

In a situation like this, the OS erases the files from its core, and saves the document in its files compartment

The hard drive on Frankie's computer is completely full. In this case, the OS deletes the files from its core and saves the document in its files' compartment because it has to produce and save a new document.

Everybody has a distinctive signature, and signatures are crucial in proving that a person actually signed a document and accepted its terms.

An operating system (OS) is the program that controls all other application programs in a computer after being installed into the system first by a boot program.

Through a specified application program interface, the application programs seek services from the operating system (API)

Therefore, the OS will erase the file from the scratch and save it in a different folder.

In Cybersecurity, vulnerability can be defined as any weakness, flaw or defect found in a software application or network and are exploitable by an attacker or hacker to gain an unauthorized access or privileges to sensitive data in a computer system.

This ultimately implies that, vulnerability in a network avail attackers or any threat agent the opportunity to leverage on the flaws, errors, weaknesses or defects found in order to compromise the security of the network.

In this scenario, a security administrator is reviewing the following information from a file that was found on a compromised host: "cat suspiciousfile.txt."

Some of the ways to prevent vulnerability in a network are;

1. Ensure you use a very strong password with complexity through the use of alphanumerics.

2. You should use a two-way authentication service.

3. You should use encrypting software applications or services.

The algorithm is as follows:

Input x

sum_b = 0

sum_c = 0

for i = 0 to 20

   sum_a = sum_a + x^i

   sum_b = sum_b + (-x)^i

   sum_c = sum_c + x^i/(i+1)

print sum_a, sum_b, sum_c

Explanation:

Required

An algorithm to solve (a), (b) and (c)

For Series (a):

This series is a geometric progression and the common ratio is x

i.e.

[tex]r = x/1 = x^2/x = ...... = x^{n+1}/x^n =x[/tex]

So, the sum of the series is:

Sum = Previous Sums + x^i --- where i is between 0 and 20 (inclusive)

For Series (b):

This series is a geometric progression and the common ratio is -x

i.e.

[tex]r = -x/1 = -x^2/x = ...... = -(x^{n+1}/x^n) = -x[/tex]

So, the sum of the series is:

Sum = Previous Sums + (-x^i) --- where i is between 0 and 20 (inclusive)

For Series (c):

This series is a neither arithmetic nor geometric progression.

It obeys the following rule:

[tex]\frac{x^i}{1+i}[/tex]  --- where i is between 0 and 20 (inclusive)

So, the sum of the series is:

Sum = Previous Sums + [tex]\frac{x^i}{1+i}[/tex]

Answer:

One approach would be to move all items from stack1 to stack2 (effectively reversing the items), then pop the top item from stack2 and then put them back.

Assume you use stack1 for enqueueing. So enqueue(x) = stack1.push(x).

Dequeueing would be:

- For all items in stack1: pop them from stack1 and push them in stack 2.

- Pop one item from stack2, which will be your dequeue result

- For all items in stack2: pop them from stack2 and push them in stack 1.

Explanation:

The following code is written in Python. It uses the numpy import to calculate all of the necessary values as requested in the question and the random import to generate random test scores. Once the array is populated using a for loop with random integers, the array is sorted and the Mean, Variance, and Median are calculated. Finally The sorted array is printed along with all the calculations. The program has been tested and the output can be seen below.

from random import randint

import numpy as np

test_scores = []

for x in range(200):

   test_scores.append(randint(55, 99))

sorted_test_scores = sorted(test_scores)

count = 0

print("Scores in Rows of 10: ", end="\n")

for score in sorted_test_scores:

   if count < 10:

       print(str(score), end= " ")

       count += 1

   else:

       print('\n' + str(score), end= " ")

       count = 1

mean = np.mean(sorted_test_scores)

variance = np.var(sorted_test_scores, dtype = np.float64)

median = np.median(sorted_test_scores)

print("\n")

print("Mean: " + str(mean), end="\n")

print("Variance: " + str(variance), end="\n")

print("Median: " + str(median), end="\n")

There are some steps with the help of which we can easily find the output half of the value for each of 5 even numbers.

Such steps are provided below:

⇒ Step 1:

Start

⇒ Step 2:

Declare three variables such as "temp1", "temp2", "count".

⇒ Step 3:

Initialize

the count variable to zero (0), i.e., [tex]count \leftarrow 0[/tex] and

the temp variable to zero (0), i.e., [tex]temp \leftarrow 0[/tex]
