USB Port 2.0
The USB (Universal Serial Bus) port is compatible with USB
devices such as keyboards, pointing devices, cameras, hard

to run simultaneously on a single computer, with some
peripherals acting as additional plug-in sites or hubs. USB
supports hot-swapping of devices so that most peripherals
can be connected or disconnected without restarting the
computer.
