Linux Disable X Window System

Q. How do I disable X Window system on boot? I just need text based interface and there is no need to waste resources on X window system. How do I disable X Window under CentOS / RHEL / Red Hat / Fedora Linux?

A. The X Window System (also known as X11 or X) is a windowing system that implements the X display protocol and provides windowing on bitmap displays. It provides the standard toolkit and protocol with which to build graphical user interfaces (GUIs) on most Unix-like operating systems.
