• A timer job runs in a specific Windows service for SharePoint Server.
• Timer jobs also perform infrastructure tasks for the Timer service, such as clearing the timer job history and recycling the Timer service; and tasks for Web applications, such as sending e-mail alerts.
• A timer job contains a definition of the service to run and specifies how frequently the service is started.
