"All Wheel Drive," is distinguished from "4-wheel drive" in that AWD is a performance enhancement and 4-WD is so you can climb rocks and stuff.
Here's a great answer for you. Go to http://www.subaru.com/sub/misc/coretech/index.html and click on the photo anywhere. This will bring up another window with more photos. The upper left hand corner is all about AWD. Click on this and THEN click on the place where it says, "Learn More." From this page, you will be able to click on links that desribe the Subaru AWD in detail.

Depending on the type of AWD system, some are full time AWD which means that the system is constantly in AWD, some systems are only part time AWD which means that either the front or rear wheels receive power until wheel slip is detected and then the system transfers power to the other axle. For example the Full Time 4WD in the Jeep vehicles is 40/60, which means that 40% of the power goes to the front wheels, and 60% to the rear unless wheel slip is occuring and then 100% of the torque can be transfered to the axle with the most traction.

AWD vehicle is a vehicle like 4X4 one. The only difference is that is a permanent All Wheel Drive. It is there for a safety feature. The Subaru started with this feature and now nearly all cars are working on something like it such as the BMW, Citroen, Hondas. Cause now the other manufacturers are realising how important this feature is. It makes the car safer. In fact from the crash tests the Subaru is the safest vehicle in its category, not only in strength but in handling as well.
The Subaru managed as well to install the ABS system in all its vehicles with the AWD (All Wheel Drive) system.
Hope this helps.

Would take too long to fully answer...here is where you want to go. http://en.wikipedia.org/wiki/All_wheel_drive
FYI - Subaru's AWD doesn't put full power to the front wheels then transfer them to the rears when there's slip (as some posters have mentioned). It is full-time AWD and all 4 wheels are given the same amount of power unless one starts to slip then the others take over (basically, the system sends power to the wheels that have grip).

This was explained to me a while ago...but I don't remember completely, but here goes...(this may encourage someone to really answer!)
The all wheel drive means the drive system can power all the wheels (really front or rear) dynamically. There are hydraulically coupled plates which, when the front spins, causes rotation between the plates which in turn transfers power to the rear. In 4 wheel drive its statically coupled (for example when the level is pulled it's a mechanical fastening) with the Subaru AWD it is dynamic, depending on the amount of slip of the front wheels.
quick summary: normally the car is front wheel drive, but when the front spins power is dynamically shifted to the rear via hydraulic coupling.
Well, that's the gist as I understand it.

All Wheel Drive
It is a vehicle where EVERY wheel is powered by the motor. In most vehicles the motor only powers the front or rear wheels.

4x4 its ALL WHEEL DRIVE. Most cars are either front wheel drive or rear wheel drive.
All wheel drive is when all the wheels are powered by your motor.
