Triggers in MySQL

Hi ,

Please can some body pinpoint exact difference between Statement Level Trigger and Row level trigger , please explain using some very simple example in both cases ?

1) How does UPDATE,INSERT Operation work in both of these type of triggers(Please
give some example).

2) What is exactly AFTER INSERT ON Table_name , does it mean after inserting some values
in trigger we fire this trigger ?

Please while explaining row level and statement level trigger give a simple example ,

thanks !!
