NEW JERSEY'S FIRST HACKERSPACE - 100 Jersey Ave, New Brunswick, NJ
This class will be focased on using the plug-in Ethernet Shield and a WiFi module using the ESP8266 module. We explore programming and communication using Arduino built-in Libraries for embedded websites on Arduino.Arduino Communications Library Functions
The W5100 chip is a complete TCP/IP processor, with 16K Bytes of packet buffer storage.
This chip provides an 10/100 Megabit Ethernet interface to the world, and a SPI interface
to the embedded microcontroller. This chip offloads all the network processing of TCP protocol
and provides raw data packets to the Arduino target CPU over an SPI interface at slower speed.

The following is a powerpoint presentation I created quite a while ago, I still think its relevant. It is a little bit old, but still very useful.Ethernet and TCP/IP Presentation
