USB devices
Your computer features four USB (Universal Serial Bus) 2.0 ports for
connecting a range of USB peripherals. See “External input devices” on
page 41 and “Printer” on page 44 for information on connecting a USB
keyboard, keypad, mouse or printer. Other common USB devices
include digital cameras, scanners, and external storage devices.
USB is plug and play, which means that you can connect and start using
a USB device without having to restart your computer. You can also
disconnect the device at any time.
A further advantage of USB is the ability to use USB hubs. This means
that several devices can share a USB port simultaneously.
