Which of the following connection types has the highest average signal degradation?

Ethernet connections are typically wired and provide stable, high-speed connections with minimal signal degradation. The physical medium of cables helps ensure that signals remain strong over short to moderate distances, making Ethernet one of the most reliable connection types without significant degradation.

DSL, or Digital Subscriber Line, utilizes existing telephone lines to deliver internet service. While it can experience some signal degradation over longer distances from the service provider, it generally maintains a more consistent quality compared to satellite connections, especially in urban areas where distances are shorter.

Cellular connections can suffer from signal degradation due to factors such as distance from the cell tower and physical obstructions. However, modern cellular technology, such as 4G and 5G, has significantly improved reliability and speed, often making cellular connections more stable than satellite ones.
