Using the USB Port
USB (Universal Serial Bus) is a hardware interface that enables you to connect multiple devices (such as
printers, mouse, keyboards, storage devices, joysticks, digital cameras, and video conference cameras,
etc.) to your notebook computer, and up to 127 devices can be attached. Besides, USB’s hot swap
capability allows everything to be plugged in and unplugged without turning the system off.
USB 2.0 offers data transfer rate up to 480Mbps (megabits per second) compared to USB 1.1 devices,
which transfer at speeds of 12Mbps. So, you could know that USB 2.0 can transfer data between the
computer and its peripherals 40 times faster than USB 1.1. However, USB 2.0 is fully backward compatible,
you will be able to use a USB 1.1 device in a USB 2.0 compliant system.
