Computer Hardware Terms, Glossary and Dictionary

USB On-The-Go (USB OTG) is a supplement to the USB 2.0 specification. USB uses Client/Server Architecture. USB OTG products can communicate with each other without the need to be connected to a PC. So one USB device acts as a USB host and the other acts as USB peripheral. Only the USB host contains the device driver and the necessary controls to transfer the data. For example, a digital camera can connect to a PDA, or a mobile phone can connect to a printer or a scanner, as long as all the devices are USB OTG-compatible. USB OTG grew from the increasing need for portable devices to be able to communicate with each other as the culture of technology moves away from a PC-centric world.
