Hello. Today I'm going to be talking a
little bit about the Task Manager. The
Task Manager lets you see what programs are running, what processes are running, and it
lets you stop programs or processes that
might be frozen and/or might be
consuming exhorbitant amounts of
resources. There are a number of
different ways that you can start the
Task Manager. You can right-click on the
Task Bar at the bottom of your screen
and choose "Start Task Manager." You can
hit Control/Alt/Delete and start
the Task Manager that way. My favorite
way of starting it is holding the control
key down, holding the shift key down, and
then hitting escape. Control/shift/escape
starts the Task Manager right up. And you
can see right now that I've got five
different applications going. You can see
what they are. In my browser I have -- I'm
open to a mail client. You can see I have
four messages I need to attend to. My
Outlook calendar. I have a Word document
open that's listing the topics that I
wish to discuss in Screencast-o-Matic
Screencast-o-Matic is actually the
program that I'm making use of. So here
I'm in Internet Explorer. I visited the
Screencast-o-Matic website and I'm in
the process of recording this video. All
of these applications are running; that's
a good thing. If you get "not responding,"
it might mean that the program is just
doing some work and it will respond if
you give it a second or two, or it might
mean that basically it's frozen it's not
going to work. If you have an application
that you wish to stop abruptly -- I'm going
to start Firefox right now just so I
have something that I can cancel. I can
end really quickly, and I'm not doing
anything in -- If you click on one of the
applications and then choose "end task" it
will end that application's running
immediately. So if I decided to end my -- um,
stop the Word application from running,
if I'd made changes to this discussing
screencast document those changes would not have been saved; it ends the process
abruptly, so you don't wish to use the
"end task" unless something seems to be
frozen, it's not responding, it's
consuming tons and tons of resources.
How do you know if a particular application
or process is consuming a lot of
resources.I can see right now I'm only
using three percent of the CPU down to 0%, 5%, 0%;
I'm not using very much at all. Physical
memory, also, I'm not used utilizing
very much: 20%. But suppose the
physical memory we're saying 80%
or 90%. Which of these,
if any of them, is the culprit? For that, I
could go to "Processes." Now you can take a look and see -- Wow at all those Chrome
processes! Do I actually have Chrome open
that many times on my computer?
No, I don't. I have opened up Chrome
process, but i have a few tabs open. Every
time you open up a new tab in Chrome
that starts a new process. I also have a
number of different extensions installed
in Chrome. Any time any of the extensions
are running, that's going to start up a
new process as well. So if you're
interested you can see these are the
different processes. These are the user
names of the owners of the process how
much CPU utilization it's using at the
moment, and at this point things are more
or less idle, how much memory is being
consumed and a description of what that
process is. If I'd like to see quickly
and easily which processes are using the
most memory, I can just click on "Memory"
to sort, so I can see that Chrome and
Internet Explorer seem to be the two
applications that are using the most
memory. Similarly, you could sort by any
of these different fields. There are
other tabs available that will give you
additional information; the contents of
those tabs, however, are beyond the scope
of this discussion. Thank you very much.
