Default Pixels and Resolution

I need someone to explain this to me, I've been doing a lot of research but I'm still confused.

If I understand this, when you take a picture witha digital camera, no matter what resolution setting you have it set at, it packs the same amt of pixels into the image.

But why if I take a picture at 600x800 can't I increase the size of the picture without losing image quality? If the same amt of pixels are in that 600x800 as would be in an 2160x1440?

I don't get it, you can scale down a large resolution picture and not lose quality, if you have a camera with sufficcient pixels, why can't you scale up?

Thanks for the clarification.

edit: Whoops, wrong forum, sorry. Please respond anyways

You got some bogus information from somewhere. Resolution is measured in pixels. In other words, an 800x600 resolution is 800 pixels wide and 600 tall. So there is a significant difference in the number of pixels in a 2160x1440 (3,110,400 or 3.1 megapixel) image than in an 800x600 (480,000 or .5 megapixel) image.

2160x1440 = 3110400
800x600 = 480000

3110400 / 480000 = 6

so it is 6 time's acurate.
