Dumb Question about Resolution

[Scot Christiansen]

I have a Nikon CoolPix 4300 and use NikonView software to view my photos on my computer display. I've found that no matter what I set the camera resolution to, the photos seem to have the same resolution on the computer screen, that is to say as I magnify the image, pixelization develops at the same level of magnifacation regradless of how fine the resolution in the photo as originally taken. This isn't what I expect to happen. What is my problem? Thank you very much for your help.
