What does "QoS" stand for in networking?

In networking, "QoS" stands for Quality of Service. This concept is essential in managing network traffic to ensure a certain level of performance, reliability, and bandwidth allocation for different types of data flows. QoS technologies help prioritize specific types of traffic over others, which is particularly important for applications such as voice over IP (VoIP) or video streaming that require a consistent and high-quality experience.

Implementing QoS can involve mechanisms like traffic shaping, prioritization, and bandwidth reservation. By ensuring that critical applications receive the necessary resources, QoS plays a crucial role in maintaining optimal network performance and user experience. This is particularly relevant in environments where different types of data compete for limited bandwidth, as prioritization can help reduce latency and packet loss for time-sensitive services.

The other choices do not accurately define QoS in the context of networking, and they do not reflect established terminology used in the industry.
