How do people raise honey bees?

According to Wikipedia:
New honeybee colonies are formed when queen bees leave the colony with a large group of worker bees, a process called swarming. The first or prime swarm generally goes with the old queen. As soon as the swarm is established as a new colony, the bees raise a new queen, or sometimes a replacement virgin queen is already present in the swarm. Afterswarms are usually smaller and are accompanied by one or more virgin queens. Sometimes a beehive will swarm in succession until it is almost totally depleted of workers.

This one is in my backyard.
