What is the name of this technique ? I need to learn more

They're called short strangles when paired as a short put and short call.  If the same strikes, it's called a short straddle. 
  
 If you want to learn more, start by reading about cash secured puts, and naked puts. Avoid selling calls because it can be pretty scary if things move against you. And of course start small and understand the risks. You'll need a lot of capital to sell options unless you stick with small priced underlyings likes AMD.
