What is USB?

USB (Universal Serial Bus) is an interface specification that was designed to allow various peripheral devices to be connected via standardized connectors.USB offers many useful and convenient features, such as the ability to connect up to 127 devices simultaneously through the use of branching devices referred to as "hubs," and the support for plug-and-play hot swapping.

USB 3.0, the next-generation USB specification was released in 2008,boosting the maximum transfer rate to 5 Gbps from 480Mbps.USB 3.0 will offer a myriad of possibilities for applications requiring fast and high-capacity communication, while maintaining compatibility with USB 2.0.
