Which of the following does a secure website use to safeguard transmitted information

Answers

Answer:encryption

Explanation:

because you can hack encrypted things well not so easily

Encryption is a secure website used to safeguard transmitted information. The correct option is C.

What is encryption?

The process of converting information into a secret code that conceals its true meaning is known as encryption.

Cryptography is the study of information encryption and decryption. In the world of computers, ciphertext refers to encrypted data and plaintext to unencrypted data.

By converting the message's content into a code, encryption serves as a confidentiality tool. Integrity and authenticity are the goals of digital signatures.

They serve to confirm the message's source and show that the content hasn't been altered.

In the process of encryption, ordinary text, such as a text message or email, is scrambled into "cypher text," which is an unintelligible format. Secure websites utilise encryption to protect sent information.

Thus, the correct option is C.

Answers

Answer:

Perfection: When you make a mistake, no one cares but you.

Even the most accomplished public speaker will make a mistake at some point. Just keep in mind that you’ll notice more than anyone in your audience. The most important thing you can do after making a mistake during a presentation is to keep going. Don’t stop and—unless the mistake was truly earth shattering—never apologize to the audience for a minor slip. Unless they are reading the speech during your delivery, the audience won’t know if you left out a word, said the wrong name, or skipped a page. Because “to err is human,” a mistake can work for you, because it allows you to connect with your audience. People don’t want to hear from someone who is “perfect;” they will relate much more easily to someone who is real.

Master the art of public speaking and crush your next presentation with one of our public speaking seminars, available online and in a classic classroom format.

Effective Executive Speaking

Take your public speaking to the next level! Speak, present and communicate with poise, power and persuasion.

Visualization: If you can see it, you can speak it.

Winners in all aspects of life have this in common: they practice visualization to achieve their goals. Sales people envision themselves closing the deal; executives picture themselves developing new ventures; athletes close their eyes and imagine themselves making that basket, hitting that home run, or breaking that record.

The same is true in public speaking. If you’ve read “10 Powerful Body Language Tips” then you know how anxiety can impact presentation skills. The best way to fight anxiety and to become a more comfortable speaker is to practice in the one place where no one else can see you—your mind. If you visualize on a consistent basis, you’ll prepare your mind for the prospect of speaking in public, and pretty soon you’ll conquer any feelings of anxiety.

Discipline: Practice makes perfectly good.

Your goal is not to be a perfect public speaker. There is no such thing. Your goal is to be an effective public speaker. Like anything else in life, it takes practice to improve those public speaking skills. We too often take communication for granted because we speak to people everyday. But when your prosperity is directly linked to how well you perform in front a group, you need to give the task the same attention as if you were a professional athlete. Remember, even world champion athletes practice every day. Try taking a class where you practice giving speeches.

However, there is a mistake: one of the numbers in the array is duplicated, which means another number is missing. Find and return the sum of the duplicated number and the missing number. Example: in the array [4, 3, 3, 1], 3 is present twice and 2 is missing, so 3 2

The program is an illustration of loops.

Loops are used to perform repetitive and iterative operations.

The program in Python where comments are used to explain each line is as follows:

#This intializes the list

nums = [5,4,4,2,1]

#This gets the length of the list

size = len(nums)

#This iterates through the list

for i in range(size):

   #The following if condition determines the repeating number

   if nums[abs(nums[i])-1] > 0:

Write a statement that slices a substring out of the string quote and puts it into a variable named selection. If given the string 'The only impossible journey is the one you never begin.', selection should contain 'possible jou' after your statement executes.

Answers

The statements that slices a substring out of the string quote and puts it into a variable named selection is as follows:

text = "The only impossible journey is the one you never begin."

selection = ""

selection += text[11:23]

print(selection)

The code is written in python.

The string is stored in a variable called text.

The variable selection is declared as an empty string. The purpose is to store our new substring.

The third line of the code is used to cut the string from the 11th index to the 23rd index(excluding the 23rd index) and add it to the declared variable selection.

Finally, we output the variable selection by using the print statement.

The bolded values in the code are python keywords.
