Connectivity
Most digital cameras can be connected directly to the computer to transfer your information. Formerly the cameras had to connect through a serial port . USB is the preferred method but some cameras use a FireWire port or Bluetooth . Most cameras are recognized as a USB storage device. Some models, such as the Kodak EasyShare One can connect to the computer via wireless network protocol for 802.11 (Wi-Fi).
A common alternative is to use a card reader that may be able to read various types of storage media and make the transfer of data to the computer at high speed. Using a card reader also prevents the battery from the camera is downloaded during the download process, as the device takes power from the USB port.
An external card reader allows direct access to appropriate images in a collection of storage media. But if it only works with a storage card, can be uncomfortable moving forward and backward between the camera and scanner. Many modern cameras offer the PictBridge standard that allows data to be sent directly to printers without the need for a computer.

Other small electronic devices (especially those used for communication) devices such as PDAs , laptops and Blackberries often contain integrated digital cameras. Also, some digital camcorders incorporate a digital camera.
Due to limited storage capacity and utility of the emphasis on the quality of these integrated devices and the majority JPEG format to store images for their great ability to compensate for the small compression quality loss it causes.
