In Windows and OSX, windows are either maximized or floating. Maximized meaning the window takes up the whole monitor, floating meaning you can move it freely around the screen. Floating windows can overlap with other windows.
Linux has these traditional desktop environments, but it also has tiling window managers. Most windows will be arranged as tiles and will not overlap. You can change the sizes of the tiles and rearrange them as you like. Sometimes you might still want a floating window and there are hotkeys to enable that for particular windows. You can also have multiple workspaces, so you can quickly move between different sets of tiles on different workspaces.
One of the main benefits of tiling window managers, in addition to looking cool as fuck, is amenability to keyboard-centric usage. In traditional desktop environments, people often rely heavily on their mouse. Tiling window managers allow you to use your mouse just as you would in a traditional environment, but also work extremely efficiently when keeping your hands on the keyboard.
