What is the primary concern associated with crosstalk?

1. Increased speed of transmission

2. Signal degradation

3. Higher data rates

4. Extended range of coverage

The correct answer is: Signal degradation

The primary concern associated with crosstalk is signal degradation. Crosstalk occurs when a signal transmitted on one circuit or channel creates an undesired effect on another circuit or channel. This interference can lead to the mixing of signals, which can result in noise and reduced clarity in the data being transmitted. Signal degradation impacts the overall performance and reliability of a network, as it can cause errors and reduce the quality of communication, making it a critical issue in network design and maintenance. In contrast to signal degradation, the other options are not directly related to the concept of crosstalk. Increased speed of transmission, higher data rates, and extended range of coverage are desirable attributes for network performance but do not address the disruptive nature of crosstalk that primarily affects signal quality. Thus, understanding crosstalk emphasizes the importance of maintaining clear signals for effective network operation.
