<summary>What is a TTY device?</summary><br><b>

TTY is short for Teletypewriter and is a virtual device file that acts as a communication interface between the user's hardware (keyboard and screen) and system processes.

Modern Usage:
- Virtual Consoles (/dev/ttyN): The full-screen command line interfaces you access via keys like Ctrl+Alt+F3.
- Pseudo-TTYs (/dev/pts/N): Emulated terminals used by windowed applications (like GNOME Terminal) or SSH sessions.
