An Introduction to Quality of Service (QoS)

Quality of Service, often abbreviated as QoS, is a collection of networking technologies and techniques designed to manage network traffic and ensure a predictable level of performance for various applications. In essence, QoS works by prioritizing certain types of data over others, helping to guarantee that critical applications receive the network resources they need, even when the network is busy. For individuals new to networking, imagine a highway system: QoS acts like traffic management, ensuring that ambulances (high-priority traffic like video calls or online gaming) can get through quickly, even if there's a lot of general traffic (like large file downloads or emails).
