>> Hey, Cybrarians, and welcome back to
00:00
the Linux plus Course here at Cybrary.
00:00
I'm your instructor, Rob Goelz.
00:00
>> In today's lesson,
00:00
>> we're going to be covering output devices.
00:00
>> Upon completion of today's lesson,
00:00
>> you're going to be able to
00:00
>> determine the output devices
00:00
that are covered on the Linux plus exam,
00:00
we're going to discuss audio output,
00:00
>> and also understand image output in Linux.
00:00
>> Audio devices allow a system to
00:00
communicate with speakers or headphones,
00:00
and generally, when you're connecting
00:00
common audio devices to Linux,
00:00
you rarely need to configure anything.
00:00
However, there are applications that require
00:00
high-quality sound cards or
00:00
use high-quality or specialty sound cards,
00:00
and these might be used for things
00:00
like advanced audio processing,
00:00
handling Dolby surround sound,
00:00
and in these cases, high-end or
00:00
new audio interface cards may not be
00:00
supported or require drivers
00:00
that are unavailable to Linux operating systems.
00:00
If you find yourself in this position,
00:00
make sure to verify from the vendor
00:00
that they have drivers for Linux and
00:00
that that hardware is compatible with
00:00
the Linux distribution that you want to run it in.
00:00
Now, in a Linux system,
00:00
there are two devices that
00:00
control the video environment,
00:00
there's the monitor and then there's the video card.
00:00
To display any graphics or text,
00:00
Linux needs to interact with both of these devices.
00:00
This is handled by the X Windows System in Linux.
00:00
Now, the X Windows System was developed by MIT in 1984,
00:00
it's commonly referred to as X or X11,
00:00
and X11 interacts with
00:00
the hardware of the system environment.
00:00
It's going to talk to the video card and monitor,
00:00
but it's also going to interact with a keyboard and
00:00
mouse so that it can display that information,
00:00
that output, to the screen.
00:00
It provides a standard interface that
00:00
desktop management software uses.
00:00
We're going to cover a lot more of this in Module 14.
00:00
But with that, we've reached the end of this lesson.
00:00
In this lesson, we covered
00:00
the output devices that are covered
00:00
>> on the Linux plus exam
00:00
>> and we talked about the audio output
00:00
>> and video output and monitors in Linux.
00:00
Thanks so much for being here,
00:00
>> and I look forward to seeing you in the next lesson.
