<a name="1206977"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">Tasks are separate threads of control, which run independently. A task describes the behavior of a discrete, separable component of an application, behaving like a separate program, except that it can communicate with other tasks. New tasks may be generated dynamically by any existing task.</font>

<p>
<a name="1206981"> </a><font size=2 face="Verdana, Arial, Helvetica, sans-serif">Applications can be broken into any number of tasks provided there is sufficient memory. When a program starts, there is a single main task in execution. Other tasks can be started as the program executes. These other tasks can be considered to execute independently of the main task, but share the processing capacity of the processor.</font>
