Wireless Internet networks, including many used in homes, often make use of high-frequency radio waves. High-frequency waves are useful because they can carry a lot of information. However, high-frequency waves are less capable of passing through objects than are low-frequency waves. As a result, waves traveling from a person's wireless laptop computer, for example, could be interrupted by objects between the computer and the modem.
Due to this limitation of high frequency waves, which of the following statements best explains why digital waves are commonly used in high-frequency wireless networks instead of analog waves?
Answers
Digital waves over analogue waves:
• Digital waves are commonly used in high-frequency wireless networks because these waves are more secure and don’t get damaged by any kind of noise.
• These waves are used in high-frequency wireless networks instead of analogue waves because digital waves are able to be transmitted over long distances as compared to analogue waves.

Answer:
It is easier to correct small disruptions in digital waves than in analog waves.
Explanation:
Digital waves are square waves, while analog waves are all other forms of waves. Many square waves can be used to mimic an analog wave. And if one or two squares are missing from the wave due to distortion, a modem or other device can often correct this small loss of information by simply ignoring it. Correcting small losses of information from an analog wave, however, is not as simple.
