You can start and stop services through the Service Configuration tool and from the command line.

Bring up the Service Configuration tool (System > Administration > Services). Some of the services are enabled and running, others are enabled but not running, some are disabled. What do enabled and disabled mean (hint: they do not mean running and stopped). Notice in the listing of services in the lefthand pane, each service name is preceded by two icons, a red or green ball (to indicate enabled or disabled) or the customize icon, and next to it a plug which either is showing plugged in (running) or not plugged in. Find a service which is enabled but not running. Which service did you find? You can confirm that it is enabled but stopped by clicking on it and looking at the information in the right hand pane above the description.
