Direct current (DC) means the electrons move in one direction.
Alternating current (AC) means the electrons flow first in one direction, then in the reverse direction, then in the first direction again - and so on - and this happens many times every second..
Another answer
Electricity is the flow of tiny particles called electrons that move through a conductor (wire). But before the electrons can flow, they need a force to get them to start moving. That force is called electromotive force (EMF) or voltage. The EMF can be produced by magnetism, friction, pressure, heat, light, and/or chemical action. The most popular source is magnetism (as is used in generators) and chemical action (as is used in batteries).
Once AC electricity has been generated in a power station, it first goes to a main transformer station where the voltage is stepped up to a very high level to be sent over long distances. It's then bumped down at other Transformers - in regional and local area sub-stations - to be distributed to businesses and homes.
In some countries they use 120 volts AC for small things like lights, coffee machines, televisions, etc. and 240 volts AC to operate large appliances like washers and dryers and other equipment such as air conditioners, water heaters and kitchen ranges. In other countries they use 230 volts AC for both small and large appliances and other equipment.
