If there is not enough resolution (image isn’t big enough) then you will see a noticeable softness to the image, or even jaggies (also called pixelization). More density = more resolution, or detail. This means how dense are the pixels (or dots).

You have heard the terms hi-resoluton, or low-resolution, or low-res.

DPI and PPI are both a way to describe resolution. Many people mistakingly talk about DPI on screen, this is incorrect, but now you will know what they mean. In an over simplification, you can think of them as the same thing, however dots refer to print and pixels are a digital display. This is where the terms DPI (dots per inch) and PPI (pixels per inch) come from. On screen you see pixels of light and in print you see dots of ink. Without overly complicating things, the resolution is what you see on screen or in print. Keep reading for more details on how to get the best results if you are ready for that info. That’s all you need to do to resize your images.
