Programming is the art of telling a machine what to do. Most machines do only one thing: a vacuum cleaner picks up dirt; a refrigerator keeps food cold, etc.
Many machines can accept simple instructions. We can set a thermostat to tell the air conditioner how cold to keep the room. We step on the gas pedal to make a car move faster. We can even control how much a hammer moves a nail by adjusting how hard we swing our arm.
Computers are a special kind of machine designed so that we can control them much more. We can give a computer a long set of instructions, and we can even ask it to make decisions.
Programming is the art of giving these instructions to a computer. Webol is a special program I've written to teach you how to program. It starts with a few simple steps and will add more and more, as you get more advanced.
