What does QoS stand for in networking?

In networking, QoS stands for Quality of Service. This term refers to the set of techniques used to manage network resources by estimating and prioritizing traffic to ensure a certain level of performance, reliability, and availability for data transmission. QoS mechanisms are vital for applications that require consistent bandwidth, low latency, and minimal packet loss, such as voice over IP (VoIP) and video streaming.

Implementing QoS allows network administrators to allocate bandwidth to different types of traffic based on their needs and requirements, ensuring that high-priority traffic receives the resources necessary to perform adequately even in times of congestion. This is crucial for maintaining the user experience across various applications and services running on a network.
