Telnet allows users to connect their computer to a remote computer over the internet and interact with it as if their local computer was directly connected to the remote system. It uses terminal emulation to determine how keyboard inputs and screen outputs will work across the connection. The telnet protocol assumes both the client and server can act as network virtual terminals to allow for remote terminal sessions over the internet.

1. Understanding Telnet
● Telnet
● terminal emulation
● Telnet protocol
● Telnet session

2. Telnet
● Your Telnet contacts
the host, using its
Internet address.

3. Terminal emulation
● It determines how
your keyboard will
transmit information
to the distant
computer and how
information will be
displayed on your
screen.

4. Telnet protocol
● This assumes that
each end of the
connection -the client
and the server- is a
network virtual
terminal(NVT)

5. Telnet session
● When the Internet
was first introduced,
they managed to
leave out the ability to
connect a terminal to
a computer across
the Internet,
