Which type of network traffic requires QoS?

Explanation:
Quality of Service focuses on giving time-sensitive traffic priority over other traffic. Video conferencing is real-time interactive communication that must travel with low latency, low jitter, and sufficient bandwidth to keep audio and video in sync. When network congestion occurs, packets from other traffic can cause delays or loss, leading to choppy audio or frozen video. Other types like email or wiki are asynchronous and can tolerate delays, and online purchasing, while interactive, generally relies on standard web traffic that can recover from minor delays. QoS works by recognizing video traffic, marking it for priority, and placing it in high-priority queues or reserving bandwidth to maintain the quality of the call.
