通用串行总线:USB (Universal Serial Bus, USB 3.0, SuperSpeed USB)


@$Part of the Peripherals glossary:@!@$ USB (Univeal Serial Bus) is a plug-and-play interface between a computer and add-on devices, such as media playe, keyboards, telephones, digital cameras, scanne, flash drives, joysticks and printe. @!USB supports hot-swapping, which mea that a new device can be added to your computer without having to add an adapter card or even having to turn the computer off. The USB peripheral bus standard was developed by Compaq, IBM, DEC, Intel, Microsoft, NEC, and Northern Telecom. The technology is available without charge for all computer and device vendo.@!@$ @!Since 1996, Windows operating systems have been equipped with USB drive or special software designed to work with specific input/output (I/O) device types. Most new compute and peripheral devices are equipped with USB.@!In November 2008, the USB Implemente Forum (USB IF) released specificatio for USB 3.0, officially known as Supepeed USB. According to Forum president Jeff Ravencraft, a USB 3.0-capable flash drive can trafer a gigabyte of data (the equivalent of two full-length movies) to a host device in 3.3 seconds. In contrast, it takes a USB 2.0-based device 33 seconds to trafer that amount of data.@!USB 3.0-capable devices are expected to be available in 2010.@!See also IEEE 1394.@!@$This was last updated in February 2012@!@$Posted by: Margaret Rouse


USB支持热交换,这意味着一个新的设备可以添加到你的电脑,而无需添加一个适配器卡甚至不得不关掉电脑。USB外围总线标准是由康柏,IBM,12月,英特尔、微软、NEC和北方电信。可用的技术是免费为所有计算机和设备vendo .
