With the "viewport" meta name, what does it do exactly? What's the difference between what it does vs Twitter Bootstrap?

In short, my 5.2" S6 screen has a resolution of 2560x1600 (in landscape), but over a smaller space than my desktop monitor of 2560x1600. Without that viewport meta directive, the phone attempts to render 1 rendered pixel per device pixel, making the site look very small and require pinching/zooming. This phone has a "Device Pixel Ratio" (DPR) of 4, meaning with the directive it will render 640x400 (2560x1600 / 4). The directive says "You have a renderable screen of 640x400, even though your screen has 2560x1600 pixels in it, effectively making the site "bigger" and easier to use by the end user.
