What is the term for the percentage of packets that fail to reach their destination, causing retransmissions and quality issues in real-time communications?

• A. Latency
• B. Packet Loss
• C. Jitter
• D. Throughput

Answer: (B)

Packet loss describes the percentage of packets that fail to arrive at their destination. It’s a measure of how many packets are lost out of the total sent, and it directly affects real-time communications because missing packets can cause glitches, gaps in audio or video, and the need for retransmissions in reliable transport protocols. Latency is about the delay time it takes for a packet to reach the destination, jitter is the variation in that delay, and throughput is the overall rate of successful data delivery over time. So the term that matches “percentage of packets that fail to reach their destination” is packet loss.
