Answer:
a. Password length, password encryption, password complexity
Explanation:
Under this scenario, the best combination would be Password length, password encryption, password complexity. This is because the main security problem is with the user's passwords. Increasing the password length and password complexity makes it nearly impossible for individuals to simply guess the password and gain access, while also making it extremely difficult and time consuming for hackers to use software to discover the password as well. Password excryption would be an extra layer of security as it encrypts the password before storing it into the database, therefore preventing eavesdroppers from seeing the password and leaked info from being used without decryption.
Answer:
Answered below
Explanation:
aFile = open("books.txt", "r")
This code uses the function open() which takes two parameters. The first parameter is the file name while the second parameter is the mode in which you are accessing the file.
The "r" mode opens the file in a reading state. That is, you can only read from the file. This code completes the reading process
aFile.read( )
The "w" mode opens the file so you can write to it and make changes.
The "a" mode opens the file so you can add contents to it.
Answer:
c) 4.4
Explanation:
You can evaluate step by step the code. You know tha your input is 4.0
Step 1 Variables definitions:
double tax;
double total;
Step 2 Ask the user for the input:
System.out.print("Enter the cost of the item");
Step 3 read de input:
total = scan.nextDouble();
Step 4 evaluate the condition ( is the input greater or equal than 3.0 ? [True])
if ( total >= 3.0)
Step 5 get done the operations inside the condition and print it:
tax = 0.10;
System.out.println(total + (total * tax));
