There are a few very important tasks associated with using the digital camera. The most important is of course capturing a beautiful photograph. The next most important task is that of transferring this image somewhere from where it can be printed. The most suitable place is hence the computer. Now, here comes another area of importance that needs to be analyzed and sufficient knowledge is required to be imparted to the users to make ample use of such an important feature. This discussion is thus generally focused upon this mechanism to transfer the digital camera images to the computer, and the various types of such a transfer. Looking from a very simple point of view, there are two methods for transferring the digital camera images to the computer; they are firstly by attaching the digital camera directly to the computer (a process that is popularly called tethering) and secondly by the use of a memory card reader.

In the present world most digital cameras are endowed with arrangements for a comparatively nippy USB connection. USB is basically an interface between a computer and peripheral devices like keyboards, telephones, scanners, and printers. In the current case this peripheral device is the digital camera. This USB feature enables the computer to be directly connected to the digital camera and transfer the images via the USB port present in the computer itself also. Many of the computer operating systems (like the Windows XP) have features for in-built tethering support for this purpose solely. One major problem of this feature of tethering is that it consumes a huge amount of power from the batteries. For this reason, many of the digital cameras are provided with AC adapter that powers the camera. The appropriate software installed within the computer and the digital cameras provides the entire task for making a successful transfer of the images from the digital camera to the computer.
