First of all DPI stands for Dots Per Inch which is more often assocated with the resolution that a printer can print at. When refering to digital cameras DPI is also a measurement of resolution. However, when discussing resolution, often times the better the resolution is the better the picture will turn out. The only problem with having a high resolution camera is that if the printer that is used to print off can't print at the same resolution that the camera took the picture at, the quality of the picture won't be as good. If you are going to look at buying a digital camera the better measure of resolution and quality is usually megapixels. It depends on what you are using the term to describe. The term photo quality really does not have a specific definition. Exact usage is dependent on the user or equipment manufacturer.
Many scanner manufacturers describe a scanner setting of 300dpi as photo quality because they say that higher settings do not enhance the quality of the resulting scanned image when stored as a .jpg image (the most common consumer picture format). Others describe 600dpi scanning as photo quality when scanning photo negatives.
Printer manufacturers describe various print resolutions as photo quality depending on when the description was written. These have included resolutions of 600dpi in the past. Many color inkjet printers tout print capabilities of over 4000dpi. Laser jet rprint resolutions seem to have a baseline of 600dpi. The subjective quality of a printed photo will depend on the technology (laserjet, inkjet, dye sublimation,etc) and quality of the printer.
Photo Quality depends both on the input source (scanned photo, scanned photo negative, etc) and the output source (computer screen, printed digital photo, etc). When using computer screens, IPODs, and digital picture frames you are using a limited number of pixels up to a bout 2 megapixels on the larger computer screeens and much less on IPODs (because of the screen size), so higher resolution will gain you nothing. For most consumer usage, scans and prints of photos made at 600dpi resolutions will be more than adequate.

What type of device will have DPI data?
DPI - is an acronym for 'dots per inch'. It usually relates to the resolution of the printed output from printers, or the input resolution of scanners.

What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
Can a short circuit current through a photo cell damage it?
If the photo cell was on during the short circuit then the chances of damage to the photo cell are at a minimum. If the short circuit occurred when the photo cell was operated then yes damage to the internal contacts of the photo cell could have happened. What happens is, the short circuit is downstream from the photo cell and when the contacts of the relay close in the photo cell the dead short is applied to the contact faces of the relay. This is somewhat like striking an arc with a welded with the same results, the contact faces weld close and the circuits breaker trips to open the short circuit. With the pole faces of the photo cell's relay closed it gives the illusion that the photo cell is not operating. The photo cell's circuitry will be working but the relay will not drop the circuit open because of the welded contact in the relay.
Can there be 600 volt single phase power?
Yes there is single phase for 600 volts. It is used for lighting. You need a transformer which gives you 600 volts plus a neutral. The voltage for the one phase to neutral is 347.
