QoS
In plain terms
Prioritizing certain network traffic to ensure performance.
Going deeper
Quality of Service manages bandwidth and prioritizes critical traffic (like voice) over less time-sensitive data to maintain quality. It allocates network resources by importance.
Under the hood
Uses traffic classification, queuing, and shaping; vital for real-time apps on congested links.
Examples
VoIP prioritization, video conferencing, bandwidth management, enterprise networks.
Think of it like...
Like an express lane reserved for ambulances so they're never stuck in traffic.
