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.

<h3>What does the AverageIfs formula find?</h3>

You can use the AverageIfs formula to find the average of a specific group of numbers from a spreadsheet based on the shared categories that these numbers fall under.

After typing in the =AverageIfs function, you then input the range from which the category will be specified. In this case that is D5:D34. The next entry would be the range the category is picked from which is B5:B34. The function will be FT for Full time workers.

The digit returned is the average salary of all full-time employees.
