So I'm kinda new to Arduino and I need an Arduino Shield Ethernet R3 to connect my Arduino UNO to the internet. I have some questions. I see that the Shield will use all my Arduino UNO pins to connect to it. Will I connect my wires of the Arduino UNO in the exact same pins of the Arduino Shield? And 2nd how is the ethernet connection working? Where will I connect the ethernet to my laptop which is one wireless or to the internet plug? These are some noob questions but please take a moment of your time to answer cause I need some help. Thank you very much.

Despite the form factor the Ethernet shield only uses some of the pins from the Arduino. (Namely pins 4, 10, 11, 12, and 13 on the Uno.) You can install the shield above the board and then connect your wires to the unused pins on top of it.

The shield in question uses the standard RJ45 cable to connect to your computer or router. If you need WiFi capabilities you might be better served looking at the WiFi shield.
So if I have a internet plug with 2 exits can I connect both computer and shield?
Thanks man.
I dont think a direct connection between the omputer and shield would work. It is generally advised to use a router/switch when connecting components.
One way around this would probably be to use a "crossover" cable that connect the rx of the computers port to the tx of the shield and vice versa.
