Difference between TCP 3 way handshake vs SSL handshake

Could someone explain what is the difference between TCP 3 way handshake and SSL handshake? Does TCP handshake establish a secure channel for data transmission? I understand that SSL handshake starts right after the TCP 3 way handshake to initiate connection to the server. Could you tell me when the tcp 3 way handshake closes the connection? is it after ssl handshake and data transmission?

Both of these are for securing a connection and finally it continues with SSL. What TCP 3 way handshake does is simply to establish connection and then SSL takes over and sustains it. May be in some configurations we do not find the TCP 3 way handshake as the SSL is suffice to make it and sustain it.

Based on our experiments, we make a conclusion that TCP with SSL is more secure, compared with TCP connection which provides reliable, ordered, error-check delivery of a stream between server and client. Due to encrypt and decrypt data, transmission speed is more slow than normal.

Thank you for your answer. Could you tell me on which OSI layer SSL handshake works exactly?
