Question

question 4 of 10
why can videos be streamed from the cloud to a computer with no loss in quality?

a. they are transmitted using digital signals and received using analog signals.

b. the cloud is closer to the computer than the source of analog signals is.

c. the signals to and from the cloud alternate between analog and digital signals.

d. digital signals are used to transmit data to and from the cloud.

Explanation:

Digital signals transmit data as discrete values, which can be reconstructed exactly without quality loss during transmission, unlike analog signals that degrade. Cloud video streaming relies on digital signals for both sending to and receiving from the cloud to maintain full quality. Options A, B, and C are incorrect: mixing analog/digital signals (A, C) would cause quality loss, and proximity (B) does not prevent quality degradation with analog signals.

Answer:

D. Digital signals are used to transmit data to and from the cloud.
