C: Both devices are using the same shared and open protocols
D: A single direct connection is established between any two devices connected to the Internet

Answer 1

Answer:

D: A single direct connection is established between any two devices connected to the Internet.

Explanation:

The internet is a complex network system made of protocols, packets, and other things. For a network to be connected, it requires the use of multiple pathways. It is unnecessary for a single direct connection because of most of the networks in this real-world travel in multiple direct connections. For example, if you want to go to Brainly.com. It first needs your IP address and then the protocols like HTTP and TCP to send it. Networks are just like traffic. If one section or a part gets blocked, they go on a different path and reach their destination. It is the same here for networks. Networks go into multiple directions to get to their destination. Therefore, a single direct connection is not required or necessary to make it possible.
