USB/USB 2.0 connector


USB Connectors

USB (Universal Serial Bus) is an input-output interface which is much faster than standard serial ports.

There are two kinds of USB connectors:

  • "Type A" connectors, which are rectagular in shape and are generally used for devices which consume little bandwidth (like keyboards, mice, and webcams);
  • "Type B" connectors, which are square-shaped and are generally used for devices with heavy bandwidth requirements (like external hard drices);
