If you're looking for a good tablet that isn't too expensive the Wacom Intuos S is a great starter, I personally use it and really enjoy it. It doesn't have a graphic screen. If you're looking for one with a graphic screen get the Wacom Cintiq 22, It's expensive but great quality. Most tablets with a graphic screen are this expensive though. But if you REALLY want one with a graphic screen that isn't TOO expensive I recommend the HUION Kamvas pro 12.

network. Firewall is also a program that screens and restricts viruses and other
users like hackers to reach the network through the internet.
