Answer:

A. True.

Explanation:

Authentication in computer technology can be defined as the process of verifying the identity of an individual or electronic device. Authentication work based on the principle (framework) 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.

Hence, if the authenticator is encrypted with the sender's private key, it serves as a signature that verifies origin, content, and sequencing.

<em>This simply means that, when a user enters his or her private key (password); the authenticator matches the private key to the uniquely defined credentials. Permission and access is granted by the authorization system right after a successful authentication. </em>

On a piano, a key has a frequency, say f0. Each higher key (black or white) has a frequency of f0 * r^n, where n is the distance
vodomira [7]

Answer:

Following are the code to this question:

import math# import math module

def RaiseToPower():   # defining a function RaiseToPower

   r= math.pow(2,1/12)    # defining r variable that calcualte the decimal point value.

   return r # return r variable value.

f0= float(input()) #defining f0 variable that hold input frequency .

for n in range(0,5):#defining for loop to count all frequency

   fn = f * math.pow(RaiseToPower(),n)    # defining fn variable that calls method RaiseToPower and multiply the value by frequency

   print(fn,end=' ')    # use print method to prints all five frequency

Output:

440

440.0 466.1637615180899 493.8833012561241 523.2511306011974 554.3652619537443

Explanation:

Description of the above python code can be defined as follows:

  • In the above code first we import the package of the math module for converting frequency, after importing package a "RaiseToPower" method is declared, inside the method r variable is declared, that counts decimal value and return its value.
  • In the next step, "f0" a frequency variable is declared that input a value from the user and defined a for loop to in the loop fn variable declared, calls the method and pass its input value and stores its decimal points and at the last print its value.
