What does QoS stand for?

• A. Quick Online Service
• B. Quality of Service
• C. Quantum of Service
• D. Quality of System

Answer: (B)

QoS stands for Quality of Service, a concept in networking that describes methods to manage and guarantee performance for different kinds of traffic. The idea is to ensure that critical applications—like voice over IP, video calls, and real-time collaboration—get the bandwidth and low latency they need, even when the network is busy. Techniques used to achieve this include prioritizing certain traffic, shaping and policing speeds, and marking packets (for example with DSCP) so routers and switches can treat them accordingly. The other options aren’t standard networking terms, so they don’t fit what QoS represents.
