USBstandard

The USB (Universal Serial Bus) standard is a widely used interface for connecting computers and electronic devices. It was developed by Intel in the mid-1990s and has since become a de facto standard for connecting peripherals such as keyboards, mice, printers, and storage devices. The USB standard defines the electrical, mechanical, and communication protocols for connecting devices.

The USB standard has undergone several revisions, with each new version offering improved data transfer rates and additional features. The original USB 1.0 standard, released in 1996, supported data transfer rates of up to 12 Mbps. USB 2.0, released in 2000, increased the data transfer rate to 480 Mbps. USB 3.0, introduced in 2008, further improved the data transfer rate to 5 Gbps. USB 3.1, released in 2013, offered data transfer rates of up to 10 Gbps. The latest version, USB 3.2, released in 2017, supports data transfer rates of up to 20 Gbps.

The USB standard also includes support for power delivery, allowing devices to be powered through the USB connection. This feature has become increasingly important as more devices rely on USB for both data transfer and power.

The USB standard is widely adopted and supported by a wide range of devices and operating systems, making it a versatile and convenient choice for connecting peripherals. Its widespread use has helped to standardize the way devices are connected, making it easier for users to connect and use new devices.
