Yes we would listen to them reading a phone book. A link for the younger listeners that may have never seen a https://en.wikipedia.org/wiki/Telephone_directory.
In today's show we continue our look at The OSI model for network communications, with examples of Layer 3 been given with particular focus on Geography diverse Host addressing.
From Wikipedia: https://en.wikipedia.org/wiki/OSI_layer_3
In the seven-layer OSI model of computer networking, the network layer is layer 3. The network layer is responsible for packet forwarding including routing through intermediate routers, whereas the data link layer is responsible for media access control, flow control and error checking.
The network layer provides the functional and procedural means of transferring variable-length data sequences from a source to a destination host via one or more networks, while maintaining the quality of service functions.
Functions of the network layer include:
Within the service layering semantics of the OSI network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.
