To transfer documents or any other data from a PC to an Android tablet, you need to connect the tablet to the PC using the USB cable that you received with the tablet. You can use any PC USB port.

After you did this, the internal memory of your tablet should appear on PC like a media storage device to which you can copy anything you want. For other methods, you can use Google to find tutorials.
