| || Facts|
At their most basic level scanners are a pc device which convert light into 0s and 1s so the computer can understand it, then convert analogue data into digital data. When buying a scanner it is important to check the resolution, because this relates to the fineness of detail that a scanner can achieve, and is usually measures in dots per inch (dpi). The more dots per inch a scanner can resolve, the more detail the resulting image will have. The typical resolution of an inexpensive desktop scanner at present is 1200 x 2400 dpi.
