What type of files do the extensions .avi, .mov, and .mpg represent?

• A. Document files
• B. Video files
• C. Audio files
• D. Compressed files

Answer: (B)

The extensions .avi, .mov, and .mpg are associated with video files. Each of these formats serves as a container to hold video data, which can include both video and audio streams. The .avi (Audio Video Interleave) format developed by Microsoft allows synchronous audio and video playback, making it a widely used format for video content. The .mov format, created by Apple for its QuickTime media player, also supports a variety of multimedia formats, heavily emphasizing quality for online and offline playback. The .mpg file extension references a format that is part of the MPEG (Moving Picture Experts Group) standard, which is commonly used for compressing video files to reduce file size while maintaining a decent level of quality. Understanding these extensions is important because they indicate the file type, which in turn informs the software needed to open and play them. The other choices represent different types of files; for instance, document files typically involve text formats, audio files consist primarily of sound data, and compressed files are used to reduce file size for storage or transmission. Thus, each extension clearly identifies the files as video, making the chosen answer accurate.
