Question: File type can be represented by

Answer:

File types can be represented by file extensions. A file extension is a suffix added to the end of a filename, separated by a period (.) character. It is typically composed of a few characters that indicate the file's format or type. For example:

- .txt represents a text file.
- .jpg or .jpeg represents an image file in JPEG format.
- .mp3 represents an audio file in the MP3 format.
- .docx represents a Microsoft Word document file.

File extensions help both the operating system and users identify the type of content contained within a file and determine which application or program should be used to open or process it.
