1 / 5
The time for a packet to travel to a host and back is the ___.
-
-
-
-
RTT, often measured by ping, captures the latency of a there-and-back journey and is a core network performance signal.
2 / 5
Variation in packet delay over time, harmful to real-time audio/video, is ___.
-
-
-
-
Jitter is the inconsistency in latency between packets; high jitter causes choppy calls even when average latency is acceptable.
3 / 5
When packets never arrive and must be retransmitted, you are seeing packet ___.
-
-
-
-
Packet loss forces retransmission and stalls protocols like TCP, badly degrading effective performance.
4 / 5
Running traceroute lists each ___ along the path so you can spot where delay is introduced.
-
-
-
-
Each hop is a router on the path; per-hop timings reveal which segment adds the latency.
5 / 5
A link can have high bandwidth yet still feel slow if it has high ___.
-
-
-
-
Bandwidth (capacity) and latency (delay) are independent; a fat but high-latency pipe still feels sluggish for interactive use.
