タイトルまたは説明

~Universal Serial Bus (USB) is an industry standard developed in the mid****0s that defines the cables, connectors and communications protocols used in a bus for connection, communication and power supply between computers and its peripherals (including keyboards, pointing devices, digital cameras, printers, external disk drives etc.)
It has become commonplace on other devices, such as smartphones, PDAs and video game consoles. USB has effectively replaced a variety of earlier interfaces, such as serial and parallel ports, as well as separate power chargers for portable devices.
The USB 2.0 specification was ratified by the USB Implementers Forum (USB-IF) at the end of ***1 achieving **0 Mbit/s and power output of max. **0mA.
The USB 3.0 specification was published on *2 November ***8. Its main goals were to increase the data transfer rate (up to 5 Gbit/s), decrease power consumption, increase power output up to **0mA, and be backwards-compatible with USB 2.0. USB 3.0 includes a new, higher speed bus called SuperSpeed in parallel with the USB 2.0 bus. The first USB 3.0 equipped devices were presented in January ***0.
 USB 3.1 increase the data transfer rate (up to *0Gbit/s) and with quick charging.
