USB 2.0/1.1 Ports
USB 3.0 Port
These USB 2.0 compatible ports (USB 2.0 is fully USB 1.1 compliant) are for low-speed
peripherals such as keyboards, mice or scanners, and for high-speed peripherals such as
external HDDs, digital video cameras or high-speed scanners etc. Devices can be plugged into
the computer, and unplugged from the computer, without the need to turn the system off (if the
power rating of your USB device is 500mA or above, make sure you use the power supply which
comes with the device).
The USB 3.0 ports are denoted by their blue color; USB 2.0 ports are colored black. USB
3.0 will transfer data much faster than USB 2.0, and is backwards-compatible with USB 2.0.
