What is a Digital SLR?
Digital SLR camera bodies (like EOS D30 or D60) look the same as the film SLR Camera bodies (like EOS Rebel). How are they different from each other? I assume that both use 35mm film but one doesn't need a scanner to upload images taken from it of course, the digital SLR. Am I right? Are there different kind of lenses used for digital SLRs?

A digital camera has a CCD (charge coupled device) in place of film. The CCD converts light intensity and color into digital information in the form of pixels. This information is stored on cards to be uploaded into your computer, and maybe edited in an imaging program.
Digital SLR's use the same lenses as their film counterparts, but without the same angle of coverage. This is because the typical CCD is not the same size as a 35-mm frame. The typical ratio of difference is 1.5. For example, a 50-mm lens on the typical digital SLR gives the coverage of a 75-mm lens (50 x 1.5=75).
