+'''S'''ecure'''SH'''ell is an enhanced [Shell] used for secure (encrypted)  communication with a remote computer. 

+[SSH] is the protocols name but it may be used to refer to the original (now commercial) implementation as well as the open source version [OpenSSH], either way, it is the preferred replacement for [Telnet]. 

 !! SSH 

 [SSH] encrypts '''ALL''' traffic. 

 The login transaction and all further traffic is secured against casual eavesdropping. 

-It is worth mentioning that '''scp''' is a '''S'''ecure '''C'''o'''p'''y program that adheres to the same principal and is usually (?) packaged with the SSH program.

 !! Telnet 

-[Telnet] is a shell '''without''' any security features (encryption). 

-Login passwords and all further transmissions are ''sent in the clear''. ie:- anyone with access to the traffic has the potential to read it.
