In regards to network performance, which characteristic should be improved to address latency issues indicated by delays ranging from 2 to 120 milliseconds?

1. Bandwidth

2. Throughput

3. Jitter

4. Packet loss

The correct answer is: Jitter

To effectively address latency issues characterized by delays ranging from 2 to 120 milliseconds, the focus should be on jitter. Jitter refers to the variability in packet arrival times across a network, which can significantly impact the performance of real-time applications such as video conferencing or VoIP. When jitter is high, packets may arrive at inconsistent intervals, contributing to perceived delays and interruptions in service. Improving jitter can stabilize the packet delivery times, leading to a more consistent experience for users. This is particularly crucial when dealing with applications that require low latency and consistent performance. By managing and mitigating jitter, you can enhance the overall user experience, reducing the effective latency perceived during communication. While bandwidth, throughput, and packet loss are also important metrics in network performance, addressing jitter directly targets the variability in packet delivery that manifests as latency, making it the most relevant characteristic to focus on in this scenario.
