ssh is a secured shell, where telnet is not a secured
one.when you ssh to trasnfer data between a system, the data
will be send in the encrypted form, where the hacker cannot
encode or decode it. While you telnet,the data send between
the system is alphabetical format(ASCII), where every one
can understand. More over as per network security, telnet
and ftp are prohibited. Always, trust SSL based data transfer.

Telnet:- Telent is a service, which works on Port 23.
Telnet and FTP both we use to access the Server or
Transferred the between Server to Server and Client to
Server. But Telnet is not secure because at Time Data
Transferred, The data Transferred in ASCII form, any Hacker
can read it and Understand easily. But as per Network
Security its Prohibited.
SSH:- As per Name SSH is Secure Shell. SSH works on port
22. SSH is the new resarch on FTP and Telnet. Purpose of
SSH is same as TELNET & FTP. But in SSH data transferred in
Encrypted mode. Encrypted means no body can ENCODE &
DECODE. If any Hacker try to hack the Data at time data
transferred through SSH, cannot ENCODE and DECODE due to
the Encryption Advantage of SSH Services.

Answer / aakash mishra
ssh is a secure way for transfering data where a hacker can
not read your data bcoz of being in incrypted form.
Telnet is not a secure way bcoz it used ASCII format which
is easily to understand.
so be alert while using the TELNET and fell free while ssh.

Answer / manoj
ssh is secure shell is providing encryption rule need
authentication. with paired keys to encryp or decrypt the
data. Also we can securely communicate or transfer file
with each other over network by copying private & public
keys with rsa & dsa.
Telnet is not secure it doesnt provide encryption rule
usually not demanding username & password..
