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.
Answer:
Physical and data link layer.
Explanation:
The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.
Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.

In my thought it's the answer of this question.
Program testing is an evaluative process which is also called Unit Testing by the programmers.
Explanation:
Software testing is an important step in the software development process. The procedure analyzes the functionality of it and if it meets the specified requirements or not. This is a four-stage procedure that involves analysis, planning, development, setting the test environment, and finally the execution of the test.
The main stages of testing that will result in an error-free and quality product are-
- Unit testing
- Integration testing
- System testing
- Acceptance testing
