Reset and Submit are special types of input buttons. Submit is used to send data to the server and Reset resets/clears the form.
<INPUT TYPE=SUBMIT>
<INPUT TYPE=RESET>
We can easily change what the buttons say.
<INPUT TYPE=SUBMIT VALUE="Send it off!"><BR>
<INPUT TYPE=RESET VALUE="Clear the form!"><P>
If required, SUBMIT button can also have a NAME. You would require this if, for whatever reason, you had more than one SUBMIT button.
