ITPEC IP October 2023 Question 25
ITPEC IP October 2023 — Question 25 of 100
Streaming begins playback after enough initial data has arrived instead of waiting for the complete video file to download. While the viewer watches, later portions continue arriving and are buffered. This reduces startup delay compared with full download and also enables live distribution.
Answer (d)
Why not others:
- (a) streaming can distribute live events without storing the full video beforehand
- (b) packet loss or inadequate bandwidth can still reduce quality or interrupt playback
- (c) some startup or buffering time is normally required, even though it is much shorter than downloading the entire file
Key rule: Streaming overlaps transfer and playback; buffering helps absorb network variation but cannot guarantee zero delay or perfect quality.
