CCD or CMOS

The first digital sensor was CCD, but lately most have been replaced by CMOS. The reason is mostly because of the price and the CMOS uses less power then the CCD. CMOS is able to produced much cheaper than the CCD sensor, the reason that they can be preduced cheaply is because they can be made at any silicon production line. The CCD have different advantages such as having less noise and more uniform output.
