. 1) A continuous stream of 0s or 1s could cause a data error. 2) Sending NRZ data over a network could cause a loss of data. 3) NRZ encoding could cause a battery to drain faster.

Sure, here are the potential problems that can occur when using Non-Return to Zero (NRZ) encoding with a continuous stream of 0s or 1s: - Long sequences of identical bits: Since there's no voltage change in NRZ encoding for a series of 0s or 1s, synchronizing the transmitter and receiver clocks can become a challenge. Bit synchronization is important to correctly identify the bit value at the receiver end (Stanford University, n.d.)[1]. - DC component problem: In NRZ, a continuous stream of zeros or ones will have a constant non-zero DC value. This DC component can cause problems with the AC-coupled links and transformers in the communication chain because they block DC components. It could further lead to loss of data and signal quality (Physics Department, University of California, n.d.)[2]. - Lack of error checking: NRZ encoding inherently lacks a mechanism for error detection. If a single bit is lost during transmission, it can disturb the interpretation of the entire data stream. - Power consumption: The signal line does not return to zero voltage between bit transmissions, hence more power could be consumed when transmitting a long series of 0s or 1s. - Ambiguity in presence of noise: If the line suffers from noise, the receiver might have difficulty in distinguishing between low amplitude '1's and '0's.
