3. Network

   • IP
     • When transmitting messages, this protocol is responsible for providing the destination address and to recognise incoming data packets.

4. Link

   • BLUETOOTH
     • This is a wireless protocol that was developed to allow devices that are very close to one another to exchange data. It works up to 10 metres, but most often the devices are within a metre of each other.
   • ETHERNET
     • Ethernet is a family of protocols responsible for sending and receiving data along a network cable. Ethernet works over a range of data speeds hence the reason for a family of protocols rather than just one.
