Answer:
=vlookup(h14, a5:h11,8,false)
Explanation:
Here, h15 is the cell in which we need the output and the value to be matched in rows to find the exact row is h14, and the range is expressed as a5:h11. Now to find the column number, we need to figure out the first and the concerned column. So, the concerned column is in which the total attendance is being listed and it is h(h14), and the first column is a. So, the column number is a=1 h=8, =8. And since we need the exact match, the value of the fourth argument is false. And thus, we have the above formula. Remember. vlookup formula is:
=vlookup(cell where the result is to be placed, range, column number in the same row as h14, exact match or approximate match). For exact match it's false, and for the approximate match, it's 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>
