USB devices
Your computer features four USB 2.0 (Universal Serial Bus) ports for connecting a range of USB peripherals. See "External input devices" and "Printer" 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.
