What could be wrong if my central air conditioning unit outside is buzzing every so often and inside is blowing air just not cold air?
your outside unit is buzzing because the low voltage control signal is activating the switch " the contactor" but your unit for some reason is not starting thus no cool air. either your circuit breaker is tripped or you may have other more serious problems. call a licensed hvac service contractor.

What should be the difference between inside and outside air be when the thermostat is set at 68 with referigated air-conditioning in the home?
Depends on the outdoor temp. If it's 75 outside, your system should easily bring your house down to the 68 degree setpoint. If it's 100 degrees outside, you'll never get there. Unless, that is, your system is too big for your home. Then it will cool you down just fine, but you'll have humidity problems...that's a whole other discussion. Most central air conditioning units are designed to maintain a 75 degree indoor temp at 55% relative humidity on a 95 degree day. So a indoor/outdoor temperature difference of about 20 degrees or so is what you should expect.

What exactly is central air conditioning I know I have AC, but what makes it central?
Central air conditioning is an air conditioning system with a central unit that distributes air to the rest of the house through vents. Some people have air conditioning units that are separate for each room, but most houses today have a centralized unit, usually located outside the home, which pumps air to each part of the house through the ventilation system. That is what is referred to as Central Air conditioning, because there is just one centralized unit cooling the entire place, as opposed to many autonomous units cooling each room.
