Final answer:
Device files on a Unix-like system are stored in the /dev directory, where each file represents a different piece of hardware.
Step-by-step explanation:
All device files on a Unix-like system are stored in the /dev directory. This directory is a special system directory that contains file representations of devices. For example, /dev/sda represents the first SATA drive, and /dev/tty represents the terminal device. Unlike the /etc directory, which contains configuration files, or the /bin directory that contains executable files, the /dev directory is specifically used to represent hardware devices as files, allowing the system and the users to interact with them using standard file operation commands.
