Answer:
Denial of service attack.
Explanation:
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.
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, sniffing, DOS attack, etc.
A denial of service (DOS) attack is a form of cyber attack that involves either the exploitation of a software flaw or overwhelmingly floods a computer system in a network with traffic in order to prevent authorized users from performing legitimate activities or transactions.
Some of the ways to prevent vulnerability or cyber attacks 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.
g 1-4 Which piece of network hardware breaks a network up into separate collision domains within a single broadcast domain
Answer:
A switch
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a hub, a router, printer, a switch, etc.
In computer networking, a switch is a network hardware (device) that breaks up a network into separate collision domains within a single broadcast domain. Thus, it's commonly configured with virtual local area network (VLAN) to break up and interconnect multiple networks.
The manager of the Super Supermarket would like to be able to compute the unit price for products sold there. To do this, the program should input the name and price of an item per pound and its weight in pounds and ounces. Then it should determine and display the unit price (the price per ounce) of that item and the total cost of the amount purchased. You will need the following variables: ItemName Pounds Ounces PoundPrice TotalPrice UnitPriceYou will need the following formulas: UnitPrice = PoundPrice/16 TotalPrice = PoundPrice * (Pounds + Ounces/16)
Answer:
The program in Python is as follows:
name = input("Name of item: ")
PoundPrice = int(input("Pound Price: "))
Pounds = int(input("Weight (pounds): "))
Ounces = int(input("Weight (ounce): "))
UnitPrice = PoundPrice/16
TotalPrice = PoundPrice * (Pounds + Ounces/16)
print("Unit Price:",UnitPrice)
print("Total Price:",TotalPrice)
Explanation:
This gets the name of the item
name = input("Name of item: ")
This gets the pound price
PoundPrice = int(input("Pound Price: "))
This gets the weight in pounds
Pounds = int(input("Weight (pounds): "))
This gets the weight in ounces
Ounces = int(input("Weight (ounce): "))
This calculates the unit price
UnitPrice = PoundPrice/16
This calculates the total price
TotalPrice = PoundPrice * (Pounds + Ounces/16)
This prints the unit price
print("Unit Price:",UnitPrice)
This prints the total price
print("Total Price:",TotalPrice)

write a script to check command arguments. Display the argument one by one (use a for loop). If there is no argument provided, remind users about the mistake.
Answer and Explanation:
Using Javascript programming language, to write this script we define a function that checks for empty variables with if...else statements and then uses a for loop to loop through all arguments passed to the function's parameters and print them out to the console.
function Check_Arguments(a,b,c){
var ourArguments= [];
if(a){
ourArguments.push(a);}
else( console.log("no argument for a"); )
if(b){
ourArguments.push(b);}
else( console.log("no argument for b"); )
if(c){
ourArguments.push(c);}
else( console.log("no argument for c"); )
for(var i=0; i<ourArguments.length; i++){
Console.log(ourArguments[i]);
}
}
The conversion rate would be the highest for keyword searches classified as Group of answer choices buyers grazers researchers browsers
Answer:
buyers
Explanation:
Search engine optimization (SEO) can be defined as a strategic process which typically involves improving and maximizing the quantity and quality of the number of visitors (website traffics) to a particular website by making it appear topmost among the list of results from a search engine such as Goo-gle, Bing, Yah-oo etc.
This ultimately implies that, search engine optimization (SEO) helps individuals and business firms to maximize the amount of traffic generated by their website i.e strategically placing their website at the top of the results returned by a search engine through the use of algorithms, keywords and phrases, hierarchy, website updates etc.
Hence, search engine optimization (SEO) is focused on improving the ranking in user searches by simply increasing the probability (chances) of a specific website emerging at the top of a web search.
Typically, this is achieved through the proper use of descriptive page titles and heading tags with appropriate keywords.
Generally, the conversion rate is mainly designed to be the highest for keyword searches classified as buyers because they're the main source of revenue for a business and by extension profits.

Write a program that removes all non-alpha characters from the given input. Ex: If the input is: -Hello, 1 world$! the output is: Helloworld
Also, this needs to be answered by 11:59 tonight.
Answer:
Explanation:
The following code is written in Python. It is a function that takes in a string as a parameter, loops through the string and checks if each character is an alpha char. If it is, then it adds it to an output variable and when it is done looping it prints the output variable. A test case has been provided and the output can be seen in the attached image below.
def checkLetters(str):
output = ''
for char in str:
if char.isalpha() == True:
output += char
return output
A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?
Answer:
Hence the answer is given as follows,
Explanation:
Base Case:-
If (num == 0) //This is the base case for the given recursive method
return 1;
If(num % 2!=0) checks whether num is odd.
The above condition is true for all odd numbers and false for even numbers.
if the remainder is not equal to zero when we divide the number with 2 then it is odd.
The method:-
The above recursive method calculates the product of odd numbers up to the given range(that is num)
For num=5 => 15(5*3*1).
For num=7 => 105(7*5*3*1).
For num=10 => 945(9*7*5*3*1).

Provide the EXACT C++ line of code necessary to return the heap-dynamic variable ptr to the operating system.
Full question:
Provide the EXACT C++ line of code necessary to return the heap-dynamic variable ptr to the operating system.
Pokemon *ptr;
ptr = new Pokemon[6];
Answer:
delete ptr;
Explanation:
The command in the answer above deallocates memory(preventing memory leaks) and returns control to the operating system.
The command in the question dynamically allocates memory to the the heap(dynamically allocated memory is called heap) while the program is running(different from statically allocated memory that allocates before program compiles). When the variable is no longer needed, deallocation occurs using the command in our answer where the variable is deleted using the pointer(keeps track of dynamic variables).
Write a program that uses a stack to test input strings to determine whether they are palindromes. A palindrome is a sequence of characters that reads the same as the sequence in reverse; for example, noon.
Answer:
Here the code is given as follows,
Explanation:

stack = []
#for strings with even length
if len(x)%2==0:
for i in range(0,len(x)):
if i<int(len(x)/2):
stack.append(x[i])
elif stack.pop()!=x[i]:
return False
if len(stack)>0:
return false
return True
#for strings with odd length
else:
for i in range(0,len(x)):
if i==int(len(x)/2):
continue
elif i<int(len(x)/2):
stack.append(x[i])
elif stack.pop()!=x[i]:
return False
if len(stack)>0:
return false
return True
def main():
while True:
string = input("Enter a string or Return to quit: ")
if string == "":
break
elif isPalindrome(string):
print("It's a palindrome")

n1 = in.nextInt();//input value
System.out.print("And another: ");//print message
n2 = in.nextInt();//input value
System.out.print("And just one more: ");//print message
n3 = in.nextInt();//input value
min = n1; //use min variable that holds value
max = n1; //use mix variable that holds value
if (n2 > max) max = n2;//use if to compare value and hols value in max variable
if (n3 > max) max = n3;//use if to compare value and hols value in max variable
if (n2 < min) min = n2;//use if to compare value and hols value in min variable
if (n3 < min) min = n3;//use if to compare value and hols value in min variable
m = (n1 + n2 + n3) - (min + max);//defining m variable that arrange value
System.out.println("Ascending: " + min + " " + m + " " + max);//print Ascending order value
System.out.println("Descending: " + max + " " + m + " " + min);//print Descending order value
}
}
Output:
Enter an integer: 8
And another: 9
And just one more: 7
Ascending: 7 8 9
Descending: 9 8 7
Explanation:
In this program inside the main method three integer variable "n1,n2, and n3" is declared that inputs value from the user end and also defines three variable "min, max, and m" that uses the conditional statement that checks inputs value and assigns value according to the ascending and descending order and prints its values.

Print the two-dimensional list mult_table by row and column. Hint: Use nested loops.
Sample output with input: '1 2 3,2 4 6,3 6 9':
1 | 2 | 3
2 | 4 | 6
3 | 6 | 9
How can I delete that whitespace?
Answer:
The program is as follows:
[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]
count = 1
for row in mult_table:
for item in row:
if count < len(row):
count+=1
print(item,end="|")
else:
print(item)
count = 1
Explanation:
This initializes the 2D list
[tex]mult\_table = [[1, 2, 3], [2, 4, 6], [3, 6, 9]][/tex]
This initializes the count of print-outs to 1
count = 1
This iterates through each rows
for row in mult_table:
This iterates through each element of the rows
for item in row:
If the number of print-outs is less than the number of rows
if count < len(row):
This prints the row element followed by |; then count is incremented by 1
count+=1
print(item,end="|")
If otherwise
else:
This prints the row element only
print(item)
This resets count to 1, after printing each row
count = 1
To delete the whitespace, you have to print each element as: print(item,end="|")
See that there is no space after "/"
Answer:
count = 1
for row in mult_table:
for item in row:
if count < len(row):
count+=1
print(item,end=" | ")
else:
print(item)
count = 1

When a database stores the majority of data in RAM rather than in hard disks, it is referred to as a(n) _____ database.
Answer:
in-memory.
Explanation:
A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to effectively and efficiently create, store, modify, retrieve, centralize and manage data or informations in a database. Thus, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.
Generally, a database management system (DBMS) acts as an intermediary between the physical data files stored on a computer system and any software application or program.
In this context, data management is a type of infrastructure service that avails businesses (companies) the ability to store and manage corporate data while providing capabilities for analyzing these data.
Hence, a database management system (DBMS) is a system that enables an organization or business firm to centralize data, manage the data efficiently while providing authorized users a significant level of access to the stored data.
Radom Access Memory (RAM) can be defined as the main memory of a computer system which allow users to store commands and data temporarily.
Generally, the Radom Access Memory (RAM) is a volatile memory and as such can only retain data temporarily.
All software applications temporarily stores and retrieves data from a Radom Access Memory (RAM) in computer, this is to ensure that informations are quickly accessible, therefore it supports read and write of files.
Generally, when a database stores the majority of data in random access memory (RAM) rather than in hard disks, it is referred to as an in-memory database (IMDB).
An in-memory database (IMDB) is designed to primarily to store data in the main memory of a computer system rather than on a hard-disk drive, so as to enhance a quicker response time for the database management system (DBMS).
