TCP/IP Configuration

To transmit data between two hosts in one network, you need two network adapters (network interface card, NIC).

One adapter sends a data packet and the other one receives it.

This is called the transport layer in the osi model.


Above this layer, you got the application protocols (http, sftp, scp, ssh,…) that are more closed to the user and are responsible for displaying received information to the user.
