Why can enlarging a image on a computer screen lower the quality of the image?

When you enlarge a picture it enlarges the pixels of the picture not the actual picture. It would be almost impossible to code a program that would enlarge the actual picture.
Put another way, you are causing less data to fill more space. This phenomenon is true even in printing. Take a nice, colorful box a product comes in and use a small microscope, such as the portable Micronta microscopes that Radio Shack used to sell, to examine it. You will discover that it looks nothing like the image and find even colors you don't see when viewing the whole image.
The more data you pack into a space, the more detail it has, so when you make it larger, you are decreasing the density of the pixels and reducing quality.

For a high quality print (300 ppi) you should be able to print 8x10 without enlarging and about 9x12 with enlarging (using an image editor to increase the pixel size about 10% to 20%). For a low quality print you can double those sizes (150 ppi).
