Which digital type requires cords?

Which digital type requires cords?

• A. CCD/MCOS/CORDS
• B. PS/PSP (still has sensor)
• C. PSP plate (wireless)
• D. CMOS (cordless)

Answer: (A)

Direct digital sensors that capture the image at the sensor and send it to the computer rely on a cable for both power and data transfer. This makes them corded. In practice, CCD sensors are inherently wired, and CMOS sensors often come in wired form as well, so they require cords during use. Indirect systems like phosphor storage plates are not connected to the computer during exposure—the plate is read later by a scanner—so they don’t use cords in the capture phase. Cordless or wireless CMOS options exist, but they don’t require cords at the moment of imaging.
