A website hosts videos that users can stream. The videos are compressed before they are uploaded. Which statement is a benefit of compressing the videos?

AData is encrypted

BThe duration of each video is reduced

CLess storage space is required on the web server ✓ Correct

DMore bandwidth is required when viewing the videos

Correct answer: (C) Less storage space is required on the web server

Explanation

Compressing a video shrinks its file size, so the web server needs less storage space to hold it.

Smaller files also travel faster, so less bandwidth is used when the video is streamed, not more.

Encryption is a separate security process that scrambles data, and compression does not encrypt anything.

The playing time of a clip stays the same after compression, since only file size falls, not duration.

The claim that more bandwidth is needed is the opposite of the true effect of smaller compressed files.

Lossy formats like MP4 discard data the eye barely notices to gain large reductions in size.
