Now, let's talk about X11. For those in the computing world, X11 is likely a familiar term. It's a windowing system that implements the X display protocol, allowing for windowing on bitmap displays. This system provides a standard toolkit and protocol for building graphical user interfaces (GUIs) on most Unix-like operating systems and OpenVMS. Additionally, it has been ported to various other general purpose operating systems.
X11 provides the foundation for building GUI environments, allowing for the drawing and movement of windows on the screen, as well as interaction through a mouse and/or keyboard. What's unique about X11 is that user interfaces are not mandated, as individual client programs handle this. As a result, we see a lot of variation in visual styling in X-based environments.
It's important to note that X11 is not an integral part of operating systems. Instead, it's an additional application layer built on top of the operating system kernel. One of the key differences between X11 and prior display protocols is that X11 was designed to be used over network connections rather than on an integral or attached display device.
One of the standout features of X11 is its network transparency. This means that the machine where an application program runs can be different from the user's local machine (the display server). This feature has been around since X11 originated at MIT in 1984. The current version, X11, was released in September 1987. Today, the X.Org Foundation leads the X project, and the current reference implementation (X.org Server) is available as free software under the MIT License and similar permissive licenses.
