Text File Identification Explained

This question asks us to identify which option represents a text file. A text file is a type of computer file that stores information as plain text characters, readable by humans and basic text editors. These files typically have extensions like $.txt$, $.log$, or $.csv$.

Analyzing File Types

Let's examine each option provided:

• $movie.mp4$: The $.mp4$ extension indicates a video file format. These files contain video and audio data, not plain text.
• $photo.jpg$: The $.jpg$ (or $.jpeg$) extension signifies an image file format. These files store visual information.
• $song.mp3$: The $.mp3$ extension is commonly used for audio files, specifically compressed music or sound recordings.
• $report.txt$: The $.txt$ extension is the standard identifier for a plain text file. This type of file contains characters that can be easily viewed and edited using simple text editors like Notepad or TextEdit.
• Option 5 is empty and therefore not a valid file example.

Conclusion on Text Files

Based on the standard file extensions and their typical uses, $report.txt$ is the only example that clearly represents a text file among the choices given.
