Moving Picture Experts Group Layer-4 is represented by which abbreviation?

• A. MP3
• B. MP4
• C. Mb
• D. MHz

Answer: (B)

Think about how MPEG versions are labeled. The fourth generation of the Moving Picture Experts Group is MPEG-4, and the common abbreviation you see for it is MP4. This shorthand is widely used not only for the standard itself but also for the popular MP4 container format that holds video, audio, and other data encoded with MPEG-4 codecs. MP3, by contrast, is MPEG-1 Layer-3 audio, not Layer-4. Mb is a megabit, a data-rate unit, and MHz is a megahertz, a frequency unit. So the abbreviation that represents MPEG Layer-4 is MP4.
