Discuss the main characteristics of the database approach and how it differs from traditional file systems.

Answers

Answer 1

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

Answers

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")

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

Answers

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

%whose average is computed.

[average_score , number_of_items] = average_of_scores_with_drops([8 6 1 2 3 5 10], 2)

Which of the following is used to encrypt web application data?
a. MD5
b. AES
c. SHA
d. DHA

Answers

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.
