   • NIC (Network Interface Card) - A device that allows a node to connect to a network.
   • Switch - This device sends the packets to the correct destination
   • A SWITCH IS UNLIKE A HUB
   • Hub - A now obsolete device considered 'stupid', as it broadcasts all data to all devices, causing security issues

   • Your standard home hub given by your ISP typically contains a combination of a modem, router, switch and WAP.
