Bytes, the higher the mega pixels, the more detail, the more bytes.
No. Raster images define images with pixels. But Vector images paint the pixels on your screen!
Computer graphics are made up of pixels. Pixels combine to form vector or scaler images.
Given that ALL computer images are formed from pixels, that would be a yes.

The Hubble Space Telescope, HST, has four cameras - three wide field (WF) cameras and one planetary camera (PC). Most images from HST is assembled from images from these four cameras, of which the PC is in the top right hand corner - that's why images from Hubble has a staggered appearance in that section of the image. Each camera uses a CCD that renders 800x800 pixels.
According to CNET the best compact digital camera are the new sleek small cameras that have touch screen built in the camera. Also, the camera's will better pixels and the higher the pixels the clearer the images will be.
No, a scanning process will result in a LARGE number of pixels not a "small number" of pixels as suggested in your question. Also images are frequently captured/stored in a compressed format (to reduce the file size), in which case there will not be a one to one match between the pixels detected by the scanning process and the stored image.

For a 12 x 12 inch print your ideal image resolution dimensions should be 3600 pixels by 3600 pixels. At a minimum your dimensions should be 1800 by 1800 pixels. Larger mega pixel producing cameras are often better when you want to crop your image down to smaller sizes.
