What is the purpose of measuring the Signal-to-Noise Ratio (SNR)?

To determine the cost-effectiveness of a network
To assess the quality of the received signal
To evaluate the speed of data transmission
To enhance the durability of cabling systems

The correct answer is: To assess the quality of the received signal

Measuring the Signal-to-Noise Ratio (SNR) is crucial for assessing the quality of the received signal in a communication system. SNR is a measure that compares the level of a desired signal to the level of background noise. A higher SNR indicates that the signal is clearer and less affected by noise, which typically leads to better performance in terms of data integrity and reliability. This makes it an essential factor in environments where signal clarity is critical, such as wireless communication, broadcasting, and data transmission. By analyzing SNR values, engineers and network specialists can diagnose issues related to signal degradation and make informed decisions on how to improve network performance or troubleshoot problems. The other options, while relevant to network performance, do not focus specifically on the purpose of SNR measurement. For example, evaluating the speed of data transmission does not directly relate to the clarity or quality of the signal itself, and determining cost-effectiveness or enhancing the durability of physical assets are considerations that arise from different aspects of network management.
