The Star physical network
How are "Voice Communications" converted to digital signals
By being broken into very small samples, and then binary values are assigned to them
Why is the TCP/IP model divided into layers
To make it easier to understand how networks work, write protocols for networks, and to create standards for networks
Why is the TCP/IP considered an "open" network model
