Minimum Workstation Standards

USB

----------------------------------------------------------------------

Short for Universal Serial Bus, USB is an external bus industry standard for attaching external devices to computers. USB Version 2.0 is the current standard. This standard allows for transfer speeds of up to 480Mbits/second. This is a complete overhaul to the Universal Serial Bus input/output bus protocol which allows much higher speeds than the older USB 1.1 standard. USB has several advantages over SCSI, including:
  • USB devices do not have to be manually numbered in the peripheral chain.
  • You can have up to 127 devices in the USB chain.
  • USB devices can be attached and removed while the devices are powered on.
  • USB devices can be powered from the USB cable eliminating the need for an A/C power source.
