Telnet is a bit of a misnomer anyway - it refers to using TCP socket 
streams on a particular numbered port (23) to log in remotely to another 
machine, whereas socket streams are more general than this and can be on 
any port and have any higher level protocol embedded in them.

I.e. Telnet uses TCP sockets, but sockets aren't always used for telnet. 
(E.g. http and ftp also use TCP sockets).
