Yeah, nobody really uses the term "closed" differential.
An open differential has no locker or limited slip. Anything else is not an open differential.

limited slip splits the percentage of torque being sent to each wheel. something like 80/20, depending on the type of limited slip. you're a member, use the search & change your avator.

Use whatever avatar you want, as long as it doesn't violate the rules (yours doesn't).
Imaging you have one tire on a high traction surface and one on a low traction surface (i.e. one tire on ice, one on asphalt).
An open differential will supply all of the torque to the wheel with the least traction (power goes to the wheel with least resistance) and you don't go anywhere. The tire that's on the ice will just sit there and spin while the other does nothing.
A limited slip differential will try to apply some torque to the slipping wheel. In this situation, the limited slip would probably apply enough torque to the high traction wheel to get you moving.
A locker (or spool) will put 50% of the torque to each wheel. Period. They have the best performance but generally come with the least street manners and a higher cost than a limited slip or open differential.
technically the rule is that it's supposed to be truck related.The Mule said:

i was just giving you a hard time...but i do like your new avator better

Actually an open differential supplies equal torque to both tires, this becomes a problem when the traction to both tires is not equal. If one tire is sitting on dry pavement and one is sitting on ice the amount of torque to each tire is limited by the amount of torque going to the tire with the least amount of traction.
A limited slip differential will overcome this equal torque distribution and supply a greater amount of torque to the tire with the higher traction. The limits of this torque bias will depend on the design and condition of the limited slip differential.
A locker mechanically ties the axles together, when locked, essentially making it one solid shaft and thus supplying 100% of the torque to the entire shaft. This can be a problem if one tire is off the ground an one side has excellent traction and doesn't have the strength to carry the full torque load=carnage.

Another example of htis would be accelerating in a turn...with an open stomp it let off whatever...the truck wont "pull" or "jump" as it will with a locker. This is because as stated the 4spider gears dont have anything causeing them to hold together, which in turn allows different gear speeds.
Now wiht a locker or such, driving into a turn or turn from a stop and accelerate. You will hear chirping adn popping because the tires are locked and it is "dragging" the rear tires. My truck is bad enough where if im driving in a curve let off hte gas i can FEEL it unlock and my truck will typically jump to the inside of the curve

aww man now i wanna see the first avatar 
i miss all the good stuff. i'd have added something here but they pretty much said it all

No he means open diff. like you just popped the cover off to cahnge it. or maybe its one of those special clear diff coverS!
