B. training is the correct answer
Answer:
a) true.
Explanation:
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
On the other hand, authentication can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle of matching an incoming request from a user or electronic device to a set of uniquely defined credentials.
Basically, authentication ensures a user is truly who he or she claims to be, as well as confirm that an electronic device is valid through the process of verification.
Digital certificates, smart cards, picture passwords, and biometrics are used to perform an authentication.
<em>Hence, in cybersecurity the use of encryption and authentication protocols is the standard method of countering attempts to alter or insert transmissions. </em>
Answer:
The program to this question can be given as:
Program:
factorial=1 #declare a variable.
number=int(input("Enter a positive integer:")) #input a number.
while (number>0): #loop
factorial= factorial*number # holding value in factorial variable
number=number-1
print('=',factorial) #print value.
Output:
Enter a positive integer:6
= 720
Explanation:
The description of the above python program can be given as:
- In the above program firstly we define a variable that is "factorial". In this variable, we assign a value that is 1 and it is used to calculate the factorial value.
- We define a variable "number". The number variable is used to take input from the user.
- Then we define a loop in the loop we calculate the factorial and hold the value in the factorial value in the last we print the value.
