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.
