The number “ENC28J60” actually only refers to a chip developed by Microchip. This chip has 28 pins and contains a complete stand-alone Ethernet controller for a 10BASE-T network connection with an SPI interface so microcontrollers like the Arduino can “talk” to it.
10BASE-T is the same connector you’ll find on your computer (if it has one) to connect with a wire to a network, where “10” indicates a maximum speed of 10 Mbit/sec. That might sound slow, but if you consider that you are using it with devices like the Arduino, then you can’t really expect massive data loads anyway. This is very responsive.
