Definition: USB, short for Universal Serial Bus, is the most common standard for connecting a digital camera to a computer for transferral of photographs. With newer operating systems and cameras, the computer should automatically find the digital camera with a USB connection. The USB 2.0 standard allows for 480 megabits per second data transfer, easily fast enough for downloading photographs for beginner- and intermediate-level digital cameras. USB 3.0 will allow for even faster connections.
Because electrical power can travel over the USB connection, some digital cameras can charge their batteries through the USB connector.
USB can make use of several different types of connectors, often using smaller-than-normal connectors for digital cameras. You have to be certain that the male connectors on both ends of your USB cable match the sockets on the digital camera and computer.
