In this session we learned about switches, routers, and firewalls.

Switches contains MAC address in hexa code where the MAC address identifies the device that is being used because it is unique. ARP allows users to convert MAC address into IP address, which is why MAC address can be faked.

Routers can make a connection between different network unlike switches. Firewalls contains details on successful or failed connection attempts, protocols, and applications in the network.
