Many digital cameras can connect directly to a computer to transfer data:
- Early cameras used the PC serial port. USB is now the most widely used method ( Most cameras are viewable as USB Mass Storage), though some have a FireWire port. Some cameras use USB PTP mode for connection instead of USB MSC; some offer both modes.
- Other cameras use wireless connections, via Bluetooth or IEEE 802.11 Wi-Fi, such as the Kodak EasyShare One.
A common alternative is the use of a card reader which may be capable of reading several types of storage media, as well as high speed transfer of data to the computer. Many modern cameras offer the PictBridge standard, which allows sending data directly to printers without the need of a computer. -Wikipedia









Most newer generation of video cameras now come with built-in still picture capabilities with the addition of a flash memory card that allows you to capture stills while taking video with the pres of a button. Though more adapted for moving pictures, the technology is almost the same with respect to the CMOS-based capture chip, the same chip that allows digital still camera’s to capture images and converting them to digital format. The pictures are stored onto memory sticks or flash drives that can be downloaded onto your computer or directly printed through card readers that are also commonplace in today’s digital world.
