At the risk of sounding elitist, you could just google it yourself.

AEG:
-trigger is pulled, circuit closes between battery and motor
-motor winds back a set of gears, pulling the piston back
-as the piston is pulled back, the "tappet plate" pulls the air nozzle back, which allows a BB to be chambered
-The gear pulling the piston back is sectored (has a range with no teeth), so once it reaches the rear position, it releases the piston
-once the piston is released, mechanical arm disengages trigger when in semi auto to stop the cycle
-piston compresses air as it moves forward, propelling the BB through the hop rubber (the bit responsible for all the range) and through the barrel

GBBR:
-trigger pulled, releases hammer which opens valve in gas magazine and locks it open
-gas rushes through air nozzle, propelling BB through the hopup and out the barrel
-as gas rushes through the air nozzle, it closes the poppet valve, redirecting the gas backwards into the bolt
-this starts the bolt moving backwards, on the way back it flips a lever which allows the gas valve on the magazine to close. And also resets the trigger.
-on the way back forward, the air nozzle picks up a BB from the magazine and chambers it

Spring:
-you pull the bolt back, piston gets locked into a sear
-push the bolt forward, piston stays in place while the cylinder moves ahead of it
-on it's way forward it picks a BB up out of the magazine and chambers it
-you pull the trigger, piston is released, compresses air as it moves forward shooting the BB through the hop and out the barrel

HPA:
-pull trigger, solenoid opens, compressed air rushes through pushing the BB through the hop and barrel. air nozzle then actuates back and forth to load a BB.
