20.4.3 USB acronyms and abbreviations
Universal Serial Bus (USB) is a standard protocol developed to connect several types of
devices to each other in order to exchange data or for other purposes. Many portable
devices can benefit from the ability to communicate to each other over the USB interface
without intervention of a host PC. The addition of the On-The-Go functionality to USB
makes this possible without losing the benefits of the standard USB protocol. Examples of
USB devices are: PC, mouse, keyboard, MP3 player, digital camera, USB storage device
(USB stick).
The USB On-The-Go block enables usage in both device mode and in host mode. This
means that you can connect to a PC to exchange data, but also to another USB device
such as a digital camera or MP3 player.
