The database system allows the creation of a single depository of information, which is updated periodically and which can be used simultaneously by many users, since this type of system allows the effective sharing of all data stored in its depository . In addition, this is a secure system and is very difficult to break into. This is because of the efficiency of the software used to maintain it. However, the use of these softwares can be a little complicated for users, in addition to requiring a high economic cost to obtain them.
The traditional file system, in turn, each user must obtain their own file related to the application they want to run. This may seem dull in comparison to the database, but it is advantageous as it does not require any spending on software, as it is simple and there are several cheap and efficient tools and editors on the market. However, this system is not so safe, it can cause isolation of data and even data inconsistency, which disrupts the entire system.
Write a program that prompts the user to input an integer that represents the money in cents. The program will the calculate the smallest combination of coins that the user has. For example, 42 cents is 1 quarter, 1 dime, 1 nickel, and 2 pennies. Similarly, 49 cents is 1 quarter, 2 dimes, and 4 pennies
Answer:
The program in Python is as follows:
cents = int(input("Cent: "))
quarter = int(cents/25)
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
dime = int(cents/10)
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
nickel = int(cents/5)
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
penny = cents - nickel * 5
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")
Explanation:
This line prompts user for input in cents
cents = int(input("Cent: "))
This line calculates the number of quarters in the input amount
quarter = int(cents/25)
This following if statement prints the calculated quarters
if quarter > 1:
print(str(quarter)+" quarters")
elif quarter == 1:
print(str(quarter)+" quarter")
cents = cents - quarter * 25
This line calculates the number of dime in the input amount
dime = int(cents/10)
This following if statement prints the calculated dime
if dime>1:
print(str(dime)+" dimes")
elif dime == 1:
print(str(dime)+" dime")
cents = cents - dime * 10
This line calculates the number of nickels in the input amount
nickel = int(cents/5)
This following if statement prints the calculated nickels
if nickel > 1:
print(str(nickel)+" nickels")
elif nickel == 1:
print(str(nickel)+" nickel")
This line calculates the number of pennies in the input amount
penny = cents - nickel * 5
This following if statement prints the calculated pennies
if penny > 1:
print(str(penny)+" pennies")
elif penny == 1:
print(str(penny)+" penny")
Which of the following is used to encrypt web application data?
a. MD5
b. AES
c. SHA
d. DHA
Answer:
b. AES
Explanation:
AES is an acronym for Advanced Encryption Standard and it is a cryptographic or symmetric block cipher that is based on a substitution-permutation network (SPN) used for the encryption of sensitive data over the internet or web. AES uses a key length of 128, 192 or 256 bits and a block length of 128 bits to encrypt data on web applications.
It is an encryption standard of the government of the United States of America and is supported by the National Institute of Standards and Technology (NIST).
Hence, AES is used to encrypt web application data and it uses an algorithm developed by Vincent Rijmen and Joan Daemen, known as the Rijndael algorithm.

Easy mapping to a new Internet Protocol (IP) address
Answer:
Option C (Assigning Internet Protocol (IP) addresses) is the correct choice.
Explanation:
DNS is a centralized process for resolving as well as continuing to give IP addresses for something like a specified domain name, a method that allows you to search a site via your web browsers whenever you tab or switch on any web server (Internet Explorer, chrome, respectively.).This helps everyone to still have throughput mostly on the network although one of the databases becomes offline for maintenance.All other options are not relevant to the situation in question. It is the right answer to all of the above.

using namespace std;
class vec//defining class vec
{
int x, y, z; //defining integer varaible x, y, z
public: // using public access specifier
vec() //defining default constructor
{
x = 0; //assign value 0 in x variable
y = 0; //assign value 0 in y variable
z = 0;//assign value 0 in z variable
}
vec(int a, int b , int c) //defining parameterized constructor vec
{
x = a; //assign value a in x variable
y = b; //assign value b in y variable
z = c;//assign value c in z variable
}
void printVec() //defining a method printVec
{
cout<<x<<","<<y<<","<<z<<endl; //use print method to print integer variable value
}
//code
vec& operator=(const vec& ob) //defining operator method that create object "ob" in parameter
{
x=ob.x; //use ob to hold x variable value
y=ob.y;//use ob to hold y variable value
z=ob.z;//use ob to hold z variable value
return *this;//using this keyword to return value
}
};
int main()//defining main method
{
vec v(1,2,3);//calling parameterized constructor
vec v2; //creating class object to call method
v2=v; //creatring reference of object
v2.printVec(); //call method printVec
return 0;
}
Output:
1, 2, 3
Explanation:
In the above-given code part, a method "operator" is defined, that accepts an object or we can say that it is a reference of the class "ob", which is a constant type. Inside the method, the object is used to store the integer variable value in its variable and use the return keyword with this point keyword to return its value.

An ISP is considering adding additional redundant connections to its network. Which of the following best describes why the company would choose to do so?
Answer:
Redundant networks are generally more reliable.
Explanation:
The complete question is in this brainly link;
https://brainly.com/question/18302186
This is based on knowing the importance of a redundant network.
C. Redundant networks are more reliable
A redundant network is one that helps to increase the reliability of a computer system. Now, this is possible because the more critical the ISP NETWORK is, the more important it will be for the time it takes to resolve from a fault would be reduced. This implies that, by adding one redundant device to their connection, the time it will take to resolve from a fault would be drastically reduced and this will lead to a far more reliable system.Thus, redundant networks are more reliable.

What do you think is the single greatest physical threat to information systems? Fire? Hurricanes? Sabotage? Terrorism? Something else? Discuss this question and provide support for your answer.
Answer:
The single greatest physical threat to information systems is:
Sabotage
Explanation:
Sabotage describes the efforts of internal persons to ensure that a system does not operate as intended or is destroyed. Among the threats to information systems, this is the greatest. The problem with sabotage is that the operators are internal, they know the system very well. They understand the weak points and the strengths of the system. They are internal terrorists to any information system. These internal saboteurs are capable of using any means to achieve their purpose. Therefore, it is necessary to scrutinize employees from time to time to discover internal risks.
Write a MATLAB function named average_of_scores_with_drops The function will have two inputs and two return values. The first input will be a list of scores. The second input will be a postive integer representing the number of scores to drop. It will not be larger than the length of the list. Your function should determine the average of the scores after dropping the specified number of lowest scores. The first return value must be a real number equal to the average score. The second return value must be the number of items that were averaged. Notes: Example Test Case: SCORES
Answer:
-%Define the function.
function [avg, ele_left] = average_of_scores_with_drops(input_list, drop_element)
%Sort the list.
input_list = sort(input_list);
%Compute the length of the list.
len_list = length(input_list);
%Declare and initialize the variable.
sum = 0;
%Increase the element to be drop by 1.
i = drop_element + 1;
%begin the for loop.
for k = i : length(input_list)
%Add the elements.
sum = sum + input_list(k);
%End of the for loop.
end
%Compute the elements left after dropping the dropped element.
ele_left = length(input_list) - drop_element;
%Compute the average of the elements left.
avg = sum/ele_left;
%End of the function defined.
end
%Run the following code in the command prompt.
%Call the function and return the average
%score and the number of elements
