<p>Explain, in simple terms, what a process is, how they relate to
|
|
applications, how some are 'system processes', and what you can do with a
|
|
process.</p>

<p>A <gui>process</gui> is a program or application being executed by the
|
|
system. When an application is launched, the system assigns a unique process ID
|
|
(PID), and its instructions and data are loaded into memory.</p>
|
|
|
|
<p>The <gui>Processes</gui> tab displays information on processes, and allows
|
|
you to <gui>Stop</gui>, <gui>Continue</gui>, <gui>End</gui>, <gui>Kill</gui>,
|
|
or change the priority of a process. If you choose to display
|
|
<gui>All Processes</gui>, the process list will include
|
|
<em>system processes</em>, which run in the background providing various
|
|
services that keep a computer running.</p>
