Which of the following statements are true?

1.A standard format for compressed video files is MPEG

2.WAV files are not compressed

3.A compressed file will be transmitted faster over a network

A1 & 2 only

B1 & 3 only

C2 & 3 only

D1, 2 & 3 ✓ Correct

Correct answer: (D) 1, 2 & 3

Explanation

All three are true about MPEG video, uncompressed WAV and faster transfer of compressed files.

Statement 1 MPEG is a standard format for compressed video files.

Statement 2 WAV audio files are stored uncompressed at full quality.

Statement 3 a compressed file is smaller, so it travels faster over a network.

Smaller file size means fewer bits to send across the connection.

Compression trades some processing effort for reduced size and quicker transfer.
