-telnet enables you to connect your terminal to another remote system
-telnet enables you to connect your terminal to the WWW
 
It has many applications.here's an excerpt from the website:
telnet communicates with another host using the TELNET protocol. If
telnet is invoked without arguments, it enters command mode, indicated
by its prompt, telnet>. In this mode, it accepts and executes its
associated commands. See , , below. If it is invoked with arguments, it
performs an open command with those arguments.
If for example a host is specified as @hop1@hop2@host , the connection
goes through hosts hop1 and hop2 , using loose source routing to end at
host . If a leading ! is used, the connection follows strict source
routing. Note that when telnet uses IPv6, it can only use loose source
routing, and the connection ignores the !.
Once a connection has been opened, telnet enters input mode. In this
mode, text typed is sent to the remote host. The input mode entered will
be either "line mode", "character at a time", or "old line by line",
depending upon what the remote system supports.
In "line mode", character processing is done on the local system, under
the control of the remote system. When input editing or character
echoing is to be disabled, the remote system will relay that
information. The remote system will also relay changes to any special
characters that happen on the remote system, so that they can take
effect on the local system. 
In "character at a time" mode, most text typed is immediately sent to
the remote host for processing.
In "old line by line" mode, all text is echoed locally, and (normally)
only completed lines are sent to the remote host. The "local echo
character" (initially ^E) may be used to turn off and on the local echo.
(Use this mostly to enter passwords without the password being echoed.).
If the "line mode" option is enabled, or if the localchars toggle is
TRUE (the default in "old line by line" mode), the user's quit, intr,
and flush characters are trapped locally, and sent as TELNET protocol
sequences to the remote side. If "line mode" has ever been enabled, then
the user's susp and eof are also sent as TELNET protocol sequences. quit
is then sent as a TELNET ABORT instead of BREAK. The options toggle
autoflush and toggle autosynch cause this action to flush subsequent
output to the terminal (until the remote host acknowledges the TELNET
sequence); and to flush previous terminal input, in the case of quit and
intr.
While connected to a remote host, the user can enter telnet command mode
by typing the telnet escape character (initially ^]). When in command
mode, the normal terminal editing conventions are available. Pressing
RETURN at the telnet command prompt causes telnet to exit command mode.

I use telnet to register to MSU for classes.
 
MSU have menus that makes it easy.however it's manually done using
keyboard, no mouse  :-(
