ITPEC IP April 2021 Question 25
ITPEC IP April 2021 — Question 25 of 100
Streaming starts playback after enough initial data has arrived instead of waiting for the entire video to download. Data continues to arrive while earlier portions are played, and a buffer absorbs ordinary variation in network delivery. This supports both stored and live content.
Answer (d)
Why not others:
- live events can be encoded and streamed while being recorded
- packet loss or insufficient bandwidth can still degrade playback
- some startup buffering is normally required, so playback is not guaranteed to be instantaneous
Key rule: Streaming overlaps transmission and playback; progressive reception replaces complete pre-download.
