From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Both are display servers which is software that allows programs to write to the screen. X is older and was created back in 1984 at MIT and Wayland is a much newer protocol that is designed to work better on newer (post 90's) hardware.
The biggest difference is that Wayland basicly allows your desktop direct access to the screen and X has a server that runs and allows your desktop to connect to it. X was originally designed to run remotely as back in the day there was one big commuter that many people connected to.
If this is all very confusing you probably should just stick to your distros defaults. Most of the time you don't need to care.
Wayland is a communication protocol that specifies the communication between a display server and its clients, designed to be a replacement for the X11 window system protocol and architecture.
I might be a little nitpicky here, but I feel it's an important distinction to make as there is no single common Wayland server like Xorg is for X11.
A display server using the Wayland protocol is called a Wayland compositor, as it additionally performs the task of a compositing window manager.
Xorg on the other hand is basically one fat display server designed like a house of cards that everyone uses.
That's a good way to put it, thank you
