Understanding Tiling Window Managers

TOS by default uses what is called a tiling window manager. What it does is rather simple.
Lets first understand what a window manager is.
A window manager is exactly what it says. It manages windows or in other words applications. It handles opening, closing, resizing and moving of applications. For exaple you can open a browser (an application) and open for example a pdf viewer. The window manager will then manage those 2 windows. Usually they are stacked ontop of eachother (the pdf viewer is ontop of the browser).
A tiling window manager is a specific way of handeling windows. When you for example open a browser it will start in fullscreen mode. When we then open up a pdf viewer the browser will be scaled to only take up half of the screen. Whilst the pdf viewer will take up the other half. Lets take a look at the difference using pictures.

Normal Window Manager

Here we show the example of the browser and pdf viewer using a normal window manager

Notice that if we open up a second window the first one resized to let the second one take up the extra space.
