What is Telnet?
In Summary:
Telnet is the protocol which enables one computer to establish a connection to another computer. The computer establishing the connection is referred to as the local computer; the computer accepting the connection is referred to as the remote, or host, computer.
Although some computers may require an account and password, many computers allow users
to access resources stored on them without an account and password. Telnet can provide
access to many resources around the world such as library catalogs, databases, and other
Internet tools and applications.
