Difference between SSH and RSH ?

Hello,

I want to know the difference between SSH and RSH ?

My few cents....

I have seen in one forum:
rsh is an old insecure protocol, which is not installed by default in
many linux distributions. Use ssh.

And some info from man page for ssh:
ssh (SSH client) is a program for logging into a remote
machine and for executing commands on a remote machine. It
is intended to replace rlogin and rsh, and provide secure
encrypted communications between two untrusted hosts over an
insecure network.

And some URL's:
