Protocols

1. Ethernet Protocol

   • Ethernet stations communicate by sending each other data frames
     • Each Ethernet station has a 48-bit MAC address - these addresses specify the source and destination of each frame
   • Use - manufacturers build Ethernet interfaces directly into PC motherboards, thus eliminating the need for a separate NIC)

2. Wi-Fi

   • Trademark for technology that allows electronic devices to connect to a WLAN
   • Examples of devices which can use Wi-Fi are: video games, smart phones and digital cameras
     • Wi-Fi compatible devices can connect to the internet via a WLAN/WAP
       • The WAP receives data from a network via physical connection. The transmitter then converts data into radio waves
         • Any device that can receive the radio waves (via a Wi-Fi adapter) allows the device to communicate or download the data from the data source (This also works in reverse).
