The holes on the back are there for quick wiring. You strip the wire and then insert it into the holes. It is held in place by spring tension. I do not recommend you wire the outlet by using these holes. From my experience the wires are not secure enough. Strip the wire and wrap it around the screws and tighten it securely which is what all the good electricians I know do. Takes a little longer but IMO it is more secure.

What is a 3 prong outlet?

Simply put, it is any electrical outlet the has three holes that the female end plugs into. What this is referred to most of the time (but not always) is a regular 110V outlet. Older outlets had only two holes, one for the hot, one for the neutral. All newer installations have the third hole for the ground wire.

Do you wire a gfci outlet differently?

No, except that you insert the wires into the holes on the back of the outlet. The power in connects to the LINE side of the outlet and power out connects to the LOAD side of the outlet. This is clearly marked on the back of the outlet. This will not only protect the outlet with the GFCI installed but all outlets receiving their power from that GFCI. If you do not want to protect the outlets receiving power from the outlet then connect that outgoing wire to the LINE side also. But know that only the outlet with the GFCI will be protected and all other outlets will not be GFCI protected.

What are the holes on the back of the outlet?

What's the question? The holes on the back of the outlet are for inserting the wire and to release it so you can pull the wire back out. There should be a round and a rectangle one for each side terminal. They only accept 14 gauge wire, not 12 gauge. Older one would accept both, but not for several years. Wire goes in the round hole and you insert something such as a small nail in the release hole and push in and then pull the wire out. The outlet will have a strip gauge on the back if the holes are for self holding lugs, and a square or round release next to the hole. You don't have to hit the release when inserting wire,only removing it. If the outlet is rated 120v, 15 or20 amp,it will hold 12ga wire.
