3. Contact the host
When you contact the host, the distant computer and
your computer
decide which terminal emulation will be used.
Terminal emulation
determine which key will transmit information.
The Telnet protocol assumes that each end of
connection is a network
virtual terminal(NVT). NVT's virtual keyboard sends
data. NVT's
virtual printer displays the information.

4. How to send the data
Typed text in a Telnet session accumulates in a buffer
on your computer.
When data is ready for transmission, or when you
give a command to transmit, the data is sent across
the Internet from your NVT keyboard.
The host's and your IP address ensure the packet,
which is sent to the proper location.
So that information can be routed back you.
Telnet commands are sent that the other NVT uses to
decide about the data.

5. Telnet
The Telnet host receives the data you've sent. It
processes the data and returns to your screen the
results of using the data or running the command on
a distant computer.
Because packets must go through many Internet
routers, a delay might occur between the time you
send a command and the time you see the results.
