To connect a USB device, insert its USB connector into an
available socket on the Raspberry Pi. You can usually do this
safely whether or not the Pi is turned on and running.
The Raspberry Pi can only supply a limited amount of power to
USB devices. It is recommended that you do not connect any
devices that draw over 100 mA. To use more power-hungry
devices, you can use a powered USB hub – a device that allows
multiple USB peripherals to be connected to a single port, and
that has its own power supply. This also allows you attach more
devices to the Pi.

Connecting to a Network
To make a wired network connection between the Pi and a
network router:
1. Plug one end of a CAT5 or CAT6 Ethernet cable
with RJ45 connectors into the Ethernet socket on
the Raspberry Pi.
2. Plug the other end of the cable into your network
router.
The actual network connection is made by the software or
operating system running on the Pi.
