>> Hi, and welcome to the CompTia A+ 200-1001 Module 1.
00:00
This is less than 1.2,
00:00
basic PC operations and introduction to the system unit.
00:00
Our objectives for this lesson are;
00:00
to understand and define
00:00
the term system unit according to what CompTia says.
00:00
Understand and recognize the basic components
00:00
of a system unit and input,
00:00
output devices, and understand
00:00
the term peripherals and give examples.
00:00
Let's go ahead and jump right in.
00:00
Understand the basic operations of the PC or system unit.
00:00
Now CompTia's definition of what we call
00:00
the PCR tower is the system unit.
00:00
Now, let's think about that for a moment.
00:00
Because over the years we've
00:00
called that system unit many,
00:00
many different things, whether it's a PC or tower,
00:00
a CPU, a box,
00:00
whatever terminology you've used,
00:00
CompTia's definition is called the system unit.
00:00
Now, the system unit is
00:00
comprised of the CPU, the hard drives,
00:00
the memory, the motherboard,
00:00
and other internal components.
00:00
The system unit provides at
00:00
its basic level processing and storage.
00:00
Those are the basic functionality
00:00
of the system unit processing and storage.
00:00
Basic usage of the system unit involves
00:00
the inputting of information and its output.
00:00
Now you think about that for a moment,
00:00
because when you're using
00:00
your system unit or your CPU or your tower,
00:00
you're basically putting in
00:00
information and you're getting an output,
00:00
basic operation of the system unit
00:00
and basic operation of a computer.
00:00
Now let's talk about what does that mean,
00:00
the inputting and the output.
00:00
How can we put things in there?
00:00
We don't open it up and put things in,
00:00
how do we input it in and how do we get things out?
00:00
We'll come to that in a moment.
00:00
Now, everything that connects to
00:00
the system unit is called a
00:00
peripheral. Now we're getting somewhere.
00:00
We have this system unit that does
00:00
the basic inputting and outputting of information.
00:00
But now everything that we connect
00:00
to that system unit is called a peripheral.
00:00
Let's dig a little bit more in.
00:00
Now, there are two types of
00:00
peripherals on input and output devices,
00:00
and we're going to talk about
00:00
those in a little bit more detail.
00:00
You got to clear understanding.
00:00
Input devices. Common input devices include mouse,
00:00
keyboards, scanners, track pads, et cetera.
00:00
If you have a digitizer pad,
00:00
that pi in a digitizer pad is an input device,
00:00
whatever you can think of that you
00:00
use to input information in.
00:00
Now, we use the keyboard to
00:00
type information into our system,
00:00
onto a Word document or a spreadsheet,
00:00
that's inputting information into that system unit.
00:00
We take a flatbed scanner and we
00:00
scan a picture and we scan it into the computer.
00:00
We're inputting information into that system unit.
00:00
The mouse, we're clicking on things
00:00
and we're inputting information in.
00:00
Anything that you can think of
00:00
that's inputting information
00:00
into that computer is an input device,
00:00
which also is called a peripheral.
00:00
Great. Let's move on to output devices.
00:00
After you put that information into the system,
00:00
it got to come out some way or unless it's stored,
00:00
and that's the basic operation of
00:00
a system unit is processing and storage.
00:00
But if it's not stored is going to come out,
00:00
and how does it come out?
00:00
It comes to the monitor.
00:00
When you connect your monitor or
00:00
that peripheral monitor to
00:00
that system unit and
00:00
you're looking at what's ever on a screen,
00:00
it's an output, it's outputting
00:00
information from that system unit.
00:00
Printers. As I was typing on
00:00
my spreadsheet earlier, I hit ''Print.''
00:00
That system unit is outputting.
00:00
It's outputting what I just print out,
00:00
so that's an output device.
00:00
Speakers. If I'm playing a whatever type of data file,
00:00
our audio file, the output coming out through
00:00
the speakers is an output, output device.
00:00
All of these devices are peripheral,
00:00
but they are output devices.
00:00
Hopefully, you're getting a basic understanding.
00:00
First, we got the CPU that it's
00:00
basic functionality is processing and storage.
00:00
Then we have to input information into that CPU,
00:00
whether it's for my keyboard,
00:00
a mouse, or whatever.
00:00
Then if it's not being stored,
00:00
it's being outputs somehow through speakers, monitors,
00:00
printers, anything that you can think
00:00
of that has an output,
00:00
that's an output device.
00:00
Basic understanding of the CPU.
00:00
This is where our journey took us today.
00:00
We found out what the system unity is.
00:00
It is the central part of the computer
00:00
that provides processing and storage.
00:00
The peripheral definition, anything input or output
00:00
into a device that's in that system unit is a peripheral.
00:00
Common input devices; keyboards, mice, scanners.
00:00
Common output devices;
00:00
mouse, monitor, speakers, printers.
00:00
Now, instead of when you walking
00:00
through Best Buy and you're
00:00
looking at mice and keyboards,
00:00
you're going to say, hey, that's an input device.
00:00
Keyboard, that's an input device.
00:00
When you're looking at speakers
00:00
and printers and monitors,
00:00
that's an output device.
00:00
It's outputting the information that I input into
00:00
my system unit and
00:00
my system unit's core functionality
00:00
is processing and storage.
00:00
Now you are beginning to talk like CompTia.
00:00
That's our lesson for today and we
00:00
will see you in the next lesson.
