Networking
What is Jitter?
Jitter is the variation in timing between packets or network responses, especially in real-time communication.
What it is
Jitter measures inconsistency in timing. Even if data is moving, uneven timing can create quality problems.
It is especially important in voice, video, and real-time applications.
Why it matters
Jitter matters because unstable timing can cause choppy calls, poor audio, video glitches, and inconsistent real-time performance.
It is one of the reasons a connection can feel bad even when it is technically online.
How it differs from latency
Latency is the amount of delay. Jitter is the inconsistency in that delay over time.
A connection may have acceptable average latency but still have jitter problems if timing varies too much.
Related questions
What is jitter in simple terms?
It is uneven timing in how network traffic arrives.
Why does jitter matter for calls and video?
Because unstable timing can make real-time communication sound or look broken.
