USB 3.0
Universal Serial Bus 3.0 (USB 3.0), marketed as SuperSpeed USB, is the third major version of the Universal Serial Bus (USB) standard for interfacing computers and electronic devices. It was released in November 2008. The USB 3.0 specification defined a new architecture and protocol, named SuperSpeed, which included a new lane for providing full-duplex data transfers that physically required five additional wires and pins, while also adding a new signal coding scheme (8b/10b symbols, 5 Gbit/s; also known later as ''Gen 1''), and preserving the USB 2.0 architecture and protocols and therefore keeping the original four pins and wires for the USB 2.0 backward-compatibility, resulting in nine wires in total and nine or ten pins at connector interfaces (ID-pin is not wired). The new transfer rate, marketed as ''SuperSpeed USB'' (SS), can transfer signals at up to 5 Gbit/s (with raw data rate of 500 MB/s after encoding overhead), which is about 10 times faster than ...

As a rule, certificates must be renewed and periodically reviewed by a certifying regulatory body responsible for the validity of the certificate's assessment methods. The certifying body can be either a state authority ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
