TELNET (Teletype Network)

Telnet

Telnet is a network Protocol used on the internet or local area networks, Typically telnet provide access to "command-line interface" on a remote host via a virtual terminal connection which consist of an 8 bit byte oriented data connection over the TCP.
Through Telnet, an administrator or another user can access someone else's computer remotely.
On the Web, HTTP and FTP protocols allow you to request specific files from remote computers, but not to actually be logged on as a user of that computer. With Telnet, you log on as a regular user with whatever privileges you may have been granted to the specific application and data on that computer.
