hi and welcome to the county l A plus 2 to 0 dash ones. Those are one module one. This is less than 1.2 basic PC operations. An introduction to the system unit.
Okay, our objectives for this lesson, our toe understand and defined the term system unit according to what camp Tia says.
Understand and recognize the basic components of a system unit and input output devices and understand the term peripherals and give examples.
So let's go ahead and jump right in. I understand the basic operations of the PC or system unit
now come to his definition of what we call the piece or tower is the system unit. Now
let's think about that for a moment, because over the years we've called that system unit many, many different things, whether it's a PC or tower, a CPU, a box, whatever in terminology you've used. Conte's definition is called the System Unit.
Now the system unit is comprised of the CPU, the hard drives, the memory, the motherboard and other internal components.
The system unit provides at his basic level processing in storage. Those are the basic functionality of the system unit processing, storage, basic usage of the system unit involves the inputting of information and its output.
Now, you think about that for a moment, because when you're using your system unit or your CPU or your tower, you're basically putting in information and you're getting an output
basic operation of the system unit and basic operation of a computer. So now it's gonna talk about what does that mean, the in putting in the output? How can we and put things in there? I mean, we don't open it up and put things in. How do we and put it in? And how do we get things out? So we'll come to that in a moment
Now everything that connects to the system unit is called a peripheral.
Okay, so now we're getting somewhere.
So we have a system unit that does the basic inputting and outputting of information. But now everything that we connect to that system unit is called a peripheral. So let's dig a little bit more Ian. Now,
there are two types of peripherals on input and output devices, and we're gonna talk about those in a little bit more detail. So you got a clear understanding
input devices
common input devices include mouse keyboard scanners, track pads, et cetera. If you have a digitized pad, that peon and that defy Tizer pad isn't input device. Umm,
whatever you can think of that you used to input information in. Now we use the keyboard to type information into our system into a word document or or spreadsheet that's inputting information into that system unit.
We take a scanner, we flatbed scanner, we scan a picture, and we scanned into the computer were inputting information into that system unit. The mouse were clicking on things, and we're inputting information in
anything that you can think of. That's inputting information into that computer is an input device, which also is caught a peripheral right. So let's move on to
output Device is after you put that information into the system, it got to come out some way unless that store and that's the basic operation of the system unit is processing storage. But if it's not stored is gonna come out, and how does it come out it come up through the monitor
when you connect your monitor or that peripheral monitor to that system unit and you're looking at what's ever on the screen.
It's an output. It's out putting information from that system. Unit printers. As I was typing on my spreadsheet earlier, I hit Print that that system unit is out putting its out putting that what I just print out. So it that's an output device. Speakers If I'm playing whatever type of
data file our audio file
and the output coming out to the speakers is an output output device. All of these devices are peripherals, but they are output devices, so hope you're getting the basic understanding. So first we got the CPU
that its basic functionality is processing a storage. Then we have to input information into that CPU, whether it's from a keyboard, a mouse or whatever. Then, if it's not being stored, it's being output somehow through speakers, monitors, printers, anything that you could think of that
has an output that's an output device.
So basic understanding of the CPU. So this is where our journey took us today. We found out what the system unity is. It is the central part of the computer de provides processing and storage on the peripheral definition, anything
input output into a device that's in that system unit is a peripheral
comment. Input devices, keyboards, my scanners, common output devices, mouse monitor, speakers, printers. So now, instead of when you're walking through Best Buy and you're looking at mice and keyboards, you're going to say, Hey, that's an input device keyboard That's an input device.
When you're looking at speakers in printers and monitors,
that's an output device. It's out putting the information that I input into my system unit and my system unit's core functionality is processing and storage. So now you are beginning to talk like camp t o.
So that's our lesson for today, and we will see you in the next lesson.
