Striker fired means that the striker and a spring provides the energy to hit and ignite the primer. It can be of the slipping sear design which is always cocked after the slide is racked or cycles or the "Glock" style which is partially cocked and is fully cocked by the trigger pull.

It is "Striker Fired" : This means that there is no single-action function for any shot, and the hammer or striker always rests in the down position until the trigger pull begins. With automatics, this means that unlike DA/SA weapons, the hammer does not remain cocked after the first round is fired, and every shot is in double-action mode.
