Final answer:
A terminal is an example of a character special file, which handles I/O in a non-buffered, character-by-character manner, unlike block devices.
Step-by-step explanation:
An example of a character special file is a terminal. Unlike block devices like hard disks and CD-ROMs, character special files handle I/O in a manner that is non-buffered and character-by-character. This means data is read or written one character at a time, making terminals (which include keyboards, mice, and serial ports for example) a fitting demonstration of such files in a Unix or Unix-like operating system.
