What causes video buffering?
Show answer & explanation
Answer: Internet speed can't keep up
Servers intentionally slow streams — Wrong. Servers don't intentionally slow streams. Buffering occurs when data arrives slower than the video plays—usually from bandwidth limitations.
Device processing is too slow — Wrong. Weak devices might struggle, but buffering typically means data arrives too slowly from the internet, not device processing issues.
Internet speed can't keep up ✓ — Correct! Videos stream data continuously—you watch while downloading. Buffering happens when internet speed can't download fast enough to keep up with playback. The player pauses to accumulate more data (buffer). Causes: slow connection, network congestion, server overload, or high-resolution video needing more bandwidth. Buffer size determines how much delay before resuming!
