SSH stands for secure shell. It looks like telnet.

The main difference between SSH and Telnet is that SSH
transparently encrypts the data between the client and the
server.

When you telnet to a router/switch/firewall/etc then it
say, type your password, every keypress of your password is
transfred across the Internet to our server in cleartext.
This means that if some person on one of the routers
through which the information passes sniffed the packets
then they'had suddenly know your password, letter for
letter!

With SSH, the information is encrypted. So when you type
your password, each letter is "scrambled" before it's sent
over the Internet, and decoded at the other end. The
encryption method is such that, if someone in between the
servers stumbled upon the information, they'd just see a
jumbled noise.

As you might imagine, this increases your security
significantly.

By default, SSH uses port 22 and telnet uses port 23

Jeetu u missed 1 thing which u told me that day..
SSH uses 3-way handshaking, whereas telnet uses simple snmp
for communicating

Answer / jm

telnet is a remote management protocol
ssh is the same but secure
SSH sends your login and password (and everything else)
converted into secret code that gets unencoded at the other
end. That way anyone that is sniffing one of the systems
involved cannot see and steal your password.

However, because SSH is encrypted it is not appropriate for
some uses. Where speed is needed, or over really bad slow
connections, or when a raw connection is needed. For
example, system administrators often use telnet to
troubleshoot other services such as webserver or email
because they can see exactly what is and is not getting sent
and received.

Also telnet is easier to include into other programs so in
cases where security is not a big deal, telnet will often be
used. Such as online games.

How does a switch use store and forward? A.) By using a Class I repeater in a collision domain B.) The LAN switch copies the entire frame into its onboard buffers and then looks up the destination address in its forwarding, or switching, table and determines the outgoing interface C.) By using broadcast addresses as source addresses D.) The switch waits only for the header to be received before it checks the destination address and starts forwarding the packets
