+ <title>What do the process statuses mean?</title>
+
+ <p>The status of a process tells you whether it is currently doing something or not. There are four statuses that a process can have:</p>
+
+ <terms>
+ <item>
+ <title>Running</title>
+ <p>Processes that are currently doing something (for example, a web
+ browser loading a web page). Running processes are those that are
+ actively using the processor (CPU).</p>
+ </item>
+ <item>
+ <title>Sleeping</title>
+ <p>Processes that are not currently doing anything (for example, because
+ they are waiting for something to happen). They don't use any of the
+ processor's time, but still take up memory. If they need to do something,
+ they will "wake up" and change their status to <em>running</em>.</p>
+ </item>
+ <item>
+ <title>Stopped</title>
+ <p>A <em>stopped</em> process is one that has been put to sleep manually.
+ You might want to stop a process temporarily if it is using too much
+ processing time, for example.</p>
+ <p>To do this, click the process in the <gui>Processes</gui> tab, then
+ right-click it and select <gui>Stop</gui> from the menu that appears. You
+ can wake it up again by clicking <gui>Continue</gui> on the same
+ menu.</p>
+ </item>
+ <item>
+ <title>Zombie</title>
+ <p>A zombie process is one that has finished running and will never start
+ again, but is being kept in the list of processes for some reason. This
+ usually happens because it was started by another program that needs to
+ know if it finished successfully or not, but which has not checked on the
+ process yet.</p>
+ <p>Zombie processes do not use any memory or processing time, and will
+ eventually go away. You do not need to do anything to get rid of them.</p>
+ </item>
+ </terms>
+
+ <p>The majority of processes will either be running or sleeping.</p>
