Which term is commonly used to describe service quality categorization in networking?

• A. Class of Service
• B. Bandwidth
• C. Latency
• D. Jitter

Answer: (A)

In networking, organizing traffic so the network can treat different types of data with different urgency is done by labeling it with a Class of Service. This concept lets you group traffic into categories like high-priority voice, medium-priority video, and lower-priority best-effort, enabling policies that prioritize, delay, or throttle traffic accordingly. Bandwidth, latency, and jitter describe performance characteristics of the network, not how traffic is categorized. So the term used to describe service quality categorization is Class of Service.
