question 1 of 25\nwhat happens to digital signals sent wirelessly over long distances?\na. the signals become weaker as they move away from the source.\nb. the signals become stronger the farther they are from the recipient.\nc. the signals are more likely to be affected by noise.\nd. the signals change so that data are less likely to be reliable.

Answer

Brief Explanations:

As digital signals travel wirelessly over long - distances, they spread out in space. This causes signal strength to decrease (attenuation), making them weaker as they move away from the source. Also, the longer the distance, the more likely they are to encounter various forms of interference (noise), and the signal quality degrades which can lead to less reliable data.

Answer:

A. The signals become weaker as they move away from the source., C. The signals are more likely to be affected by noise., D. The signals change so that data are less likely to be reliable.
