The Internet is made up of millions of LANs and WANs, connected together in a semi-mesh format.

Packets are not received & transmitted to every device connected to the internet. Information related to the destination is embedded in the routing tables, routers connected to the web. The hardware layer is responsible for converting alpha/numeric messages into a digital signal and sending the message through the telephone’s path. After necessary processing at the TCP level, the packets move towards the IP layer. The IP layer provides the destination layer where the message should be received. At this level, message packets retain port number as well as IP address.
