Which of the following represents the biggest difference between asymmetric and symmetric cryptography? A. Asymmetric uses a short string of data for encryption, and symmetric uses a long string of data.
B. Asymmetric uses tokens for encryption, and symmetric uses a short string of data.
C. Asymmetric uses random numbers for encryption, and symmetric uses mathematical algorithms.
D. Asymmetric uses two different keys for encryption, and symmetric uses one shared key.

D

Explanation:

The basic difference between these two types of encryption is that symmetric encryption uses one key for both encryption and decryption, and the asymmetric encryption uses public key for encryption and a private key for decryption.

answer; its the top layer;

answer is:

a). backstage view

explanation:

backstage view is the area where files and data about them is managed— creating, saving, printing, sending to others, inspecting for hidden metadata or personal information, and setting options. so in this way we can add many things to our document swiftly.
