All right, so now in this module will talk about evaluating components.
00:12
So we want to build our own PC. We're going to start from scratch.
00:19
So a few of the things that you want to do first is look at technical specifications, read reviews online. So you kind of have an idea of what kind of pc you wanna build. You start looking at part, you know, look at reviews on lines of
00:31
how other people like the parts, look at the prices. And
00:37
But before we do that, we need to know what kind of PC we're gonna build. What are we gonna use our PC for?
00:43
So
00:44
if we use our PC as immediate workstation,
00:48
some of the things, uh, some of the common formats for Media workstation or your graphic work stations,
00:54
which are for like, you use with the digitize er or some kind of stylist device. You're gonna create art.
01:00
You create graphics
01:03
that could be considered graphics workstation, digital audio workstation you're using the computer to record
01:10
could be high end recording, such as for a movie or for in a studio recording, music
01:17
and a video work station. If you're gonna edit videos together to create a final product.
01:25
So if we're gonna do a graphics workstation, some of the things we need to consider
01:29
when it comes to the part we're going to use,
01:32
you want to make sure we have a high quality monitor. So if we're gonna do artwork, we need to be able to make sure the color is the color we really want. So you want to make you have a high quality monitor that's gonna accurately display the kind of colors you're choosing, actually Show the lines crisp and clear,
01:49
graphics works, takes up a lot of CPU power.
01:53
So you you definitely want to look at having a multi core CPU, one that has multiple,
02:02
and you also want to consider having it be a 64 bit because you're moving a lot of data around and you're not.
02:08
And all that data is being stored in RAM. So with 32 bit Os is you can only start before gigs of data and ran before it starts going to the hard drive, which is slower than your ram. So you're going to graphics processing.
02:23
You're easily gonna fill that four gigabytes up, especially with very large images. So 64 bit will allow you to go beyond that. Forget about gigabit boundary. So you have a lot faster performance when drawing. You know what? I draw something and then wait for it to appear on the screen for a few seconds.
02:38
And then when you go to finally save that image to the hard drive, it's still gonna be
02:44
very large, especially when you're first working with them because you don't compress him until later cause compressing an image will
02:50
degrade the quality of it. So you're gonna be a lot of hard drive space.
02:57
And since we're dealing with graphics and colors
03:00
and a lot of video, you're gonna want a high end GPU, which means graphics processing units. You want to make sure you have a really good video card.
03:15
So if we're doing a lot of work with audio safe
03:17
where ah,
03:20
in our own band and we want to record our own music
03:23
or you don't professionally in a studio
03:28
for a workstation focused on digital audio,
03:30
it's gonna have much of the same requirements as a graphics workstation
03:36
because un compressed audio still takes up a lot of space
03:42
So you're also gonna want to have a lot of rim, just like in the graphics workstation instead of a digitized to draw on your own a lot of, ah, high end video, high end audio card.
03:51
So
03:53
video car that comes on the motherboard will definitely not be sufficient for
03:58
a digital audio workstation.
04:00
They make audio cards there are developed for this market,
04:06
and they usually come with an external
04:10
external peripheral such as this one, which will allow you to plug in multiple audio devices.
04:15
So standard sound cards just gonna have maybe one line in
04:19
and then it's gonna have a bunch of outs for maybe surround sound headphones.
04:24
But if we're doing a lot of work with audio, we're probably gonna have multiple sound sources coming into our device. We need a special kind of device to handle that.
04:32
In this case right here, we can see there's four different inputs to plug in audio, and then we can even change the levels of the sound quality,
04:45
and this would usually plug in via USB.
04:51
We're working with videos. We're gonna make some, we're gonna do a lot of home movies or we're doing it professionally
05:00
a lot of the same requirements that we just talked about with the audio and graphics.
05:03
But also consider a raid.
05:06
Technology, which is striping. Multiple drives together
05:11
specifically rate zero
05:13
because it'll give you more storage space and also give you a lot faster
05:18
read and write times
05:23
now, just like we had specialized audio for special audio card for video, adding. There's also a special video cars for video editing that you have multiple inputs for video sources,
05:33
like a standard video card only has video out. So I'm gonna let you plug it into a monitor
05:40
or maybe out h D M I to a TV.
05:44
But you want to consider with the specialized video card that will have inputs for common L. A. To put video into the computer
05:51
from various sources.
05:57
Video editing software usually requires special keyboards to that
06:01
have a lot of shortcuts for performing common actions and video editing software like cuts and transitions.
06:12
And this is in multiple moderns is very important for video dating
06:17
because you're gonna look at it if your video editing you have the video ah, one screen full size that you can kind of review as you play it, and then on the other screen you can set. Okay, This is where I want to cut this video, and then I want to move it to this part of the movie or another part. So or if you're looking at multiple video sources at once, you have multiple videos
06:38
across both monitors, so
06:40
multi motors are almost a must for video
06:43
editing.
06:46
No more time for the home user, especially for someone like me is a gaming PC.
06:51
So it was everything that I said for those other three. Definitely apply, except the specialized cards.
06:58
The two biggest focus for game PC or your CPU and your GP you. So you definitely want to have a fast de puta as multiple course,
07:06
and you also want to have not just multiple cores. The actual speed of the CPU itself needs to be
07:12
fast
07:14
and current technology. Right now we're looking up around at least three gigahertz. You should have for speed for your processor
07:21
now G P. Used for our video cards gaming video cards to become a huge market,
07:28
and they have stats that
07:30
they have stats that match PCs from three years ago now that are on a single card so they'll have their own processors that do graphic processing that start running up to like 1 to 2 gigahertz and speed.
07:42
And some of them even support multiple cores themselves.
07:46
It's not uncommon to see
07:48
512 megabytes of RAM on a
07:53
or even up to a gig of RAM on a video card.
07:57
And these are all focused to processing
08:01
three D graphics, which is what we see in Game. So to make our games look more realistic, these cards air
08:09
designed to do that
08:15
the price of these cards can run up to $1000 for a high end video card. Almost you could. You could buy a mid range the low range PC for the price of these high end graphics cards.
08:33
Besides the graphics card in the CPU, a nice sound card's good, so you definitely wanna have a high definition audio sound card.
08:41
A lot of these games are like movies now, so we'll have full surround sound. You're playing a
08:46
shooter game. You'll hear the guy shooting from behind you if you have ah
08:50
surround sound or you hear a plane come flying from behind to the front of you. So you want to have
08:56
high quality sound card that supports multiple channels
09:00
and higher sample rates means the sound quality will be better.
09:03
Same for the bits
09:07
now the same kind of people usually do. Gaming workstations also do
09:11
over clocking, which is
09:13
making your processor run fast. It's supposed to,
09:16
and these graphics cards also get really warm seas. They're having really hot processing a really hot graphics card. You're gonna start getting a lot of heat in your case.
09:24
So you really want to pay attention to cooling on gaming PCs, whether it be more fans, more efficient heat sinks or the far extreme using liquid cooling, which is basically using water through pipes
09:39
to cool the components
09:43
you don't have a good A good sized monitor should be a minimum of 1920 by 10 80 Resolution,
09:50
which is the same resolution. See for Ah, hi def movie,
09:54
and the side should be about 24 inches
09:56
bare minimum four gigabytes. Ram, Just like with the graphics workstations, the video workstations
10:03
lot Dad's gonna be stored in rim, and the hard drives will slow it down. Hard. Drive's not as big of a deal as it is in the other workstations, because most games or read only you're not doing a lot of writing, so the games start taking up a lot of space on their own.
10:18
But once you play them, they're not gonna take up much more space.
10:24
So you just need a basic hard drive. Configuration
10:26
is that is big enough to hold how many games you won't install that sufficient
10:33
home theater system. So you want to use your PC now that we have all these streaming technologies such as Netflix Amazon Video, there's a lot of streaming technology out there.
10:45
Who, Lou.
10:46
A lot of people now want to be able to plug their PCs
10:50
into their home theater system. So to do this, make sure that you have video card that supports what you're plugging in to see if your home theater has a projector.
11:00
Make sure that the connections of the projector match the connectors on the sound car and vice versa,
11:05
like some old projectors might only have like a VJ out some new ones. One of H D m. I
11:15
make sure you have a good sound card
11:16
to emulate the cause a lot of computers now, have you? And blue raising him like we mentioned. So you won't be able to get that full some 0.1 surround sound to make sure you have a sound card that supports it. If you have a motherboard with the high definition audio standard on its sound card, it'll be good enough for home theater.
11:37
Well, things to consider The sound card, though, is if it will have had the outputs necessary to plug into your surround sound system. You already have a stereo system. You're not just going into a TV
11:50
and network connection, So
11:52
why do you think Network connections A concerned with Home theater systems Wireless First is wired.
12:01
So as we mentioned before the video file start, getting video is becoming very large. You look at the size of the video stored on a blue ray disc that's considered high death. When you look at hi def channels,
12:13
those were really big files. So
12:15
you really want to look at how you're gonna stream that video to your home theater? Because if you're gonna do a lot of high def videos that you're streaming, we wanna be our play your favorite service, your favorite video serving service at the high def resolution. You have to have the band with support it.
12:30
And with wireless, you know, always guaranteed to have a lot of speed, especially depending on where your PC is located. It's a lot of people would have their wireless router,
12:39
you know, in their home office. Wait, maybe on the way other side of the house
12:43
from where they're living room is in the home theater PC and you may see that. Okay,
12:48
with what? With WiFi. I don't have enough speed to get high definition because the further you are away from the access point with WiFi lower the speed is gonna be.
12:58
So your options there are maybe by another
13:03
wireless access point that's closer
13:07
or determined some way to run
13:11
the cable to it from your
13:13
home router.
13:15
But that's an important thing to consider.
13:20
I had that problem all the time. I ended up running a cable across the house,
13:26
annoying me. The video starts going where the waves can tell is video start getting choppy
13:31
made pause like it's buffering.
13:33
But then, if you go like a PC that's plugged in, it plays fine. It's probably your wife, especially. It's far away and the more walls that are between you and the WiFi router
13:45
talking about regular desktop PCs In general, there's two types. We have a thick and thin client.
13:52
That client is your typical PC, a typical desktop.
13:56
I think of this in terms of corporate. You know, you have a bunch of peace, ese. You wanna push out to your users,
14:03
you should make sure they're all the same. Provide for easier maintenance that everyone has the same configuration. Same kind for your favorite vendor.
14:11
I don't need anyone specifically,
14:13
but *** clients through all the processing on their own. So they have been talking about si, pues. We talk about graphics card, everything that clients have all those parts, like the other kind of work station we mentioned. They all sit locally, so all the work is done locally. If you're just doing a basic configuration for office type work running, we're processing
14:33
and spreadsheets.
14:35
These are some recommended stats with these stats
14:39
are just based on today's technology. So about two gigs of RAM, 20 days of hard drive space. You don't need a high speed process you to do.
14:46
We're, um,
14:48
office documents.
14:52
Now we say 64 bit processor, not only
14:56
because off,
14:58
not because we're gonna do any kind of high processing that's gonna take up a lot of RAM or high activity, but it's becoming the new standard. And in the next couple years,
15:07
the newer version of OS coming out, we're only gonna be 64 bits, so you should buy 64 bit.
15:13
And to be truthful, you be probably hard pressed to find a process you have to go out of your way to buy a desktop that wasn't
15:18
64 bit compatible. Now
15:22
direct X nine graphics The direct It's nine is
15:26
Microsoft's protocol for doing graphics.
15:30
It's kind of, ah, common programming language for developers to use.
15:35
So when did they have? They can use predefined
15:37
functions to develop graphics without having to create their own programming language.
15:43
And so drivers for the video cards are designed to take advantage of that programming language.
15:54
But what it really comes down to is
15:56
you want to make sure that you're at least meeting the minimum specs for whichever operating system
16:03
and applications are playing to run on that desk, top.
16:07
So first you look at the operating system. So are using UNIX and Windows.
16:12
And what are the minimum specs to run that
16:15
operating system? But then also look at the kind of applications you expect your users
16:22
to be opening on a daily basis and look at those minimum requirements. Those might be a good chance. A lot of these applications will have a higher minimum requirement.
16:30
Then the actual operating system does,
16:33
and then look at the minimum requirements and then probably go up a notch from those minimum requirements because those are the bare minimum. So, yeah, it's gonna run, but probably not,
16:42
not nice. So that's something really want taken consideration.
16:47
So a lot of heart. A lot of software companies and allow the operating systems will give you the bare minimum. But then they also tell you recommended
17:00
now the reverse of a thick clients, a thin client.
17:03
That's where you just have a basic PC. It's usually a small form factor.
17:10
It doesn't do much of the work there. What does it go back to?
17:14
A central server that's doing all the work for us,
17:17
so those requirements are usually a lot less because it's not all needs enough processor power to grab something over the network
17:25
and displayed on a screen. All the work is really being done
17:29
at the other end.
17:30
On some kind of server
17:33
Go.
17:36
You see this lot in commercial environments for,
17:40
like, cash registers
17:42
point of sale systems.
17:45
Excuse me,
17:47
but the key is it says the bare basics and everything else is gonna be
17:51
everything's gonna be done in a central location.
17:53
It's a lot easier to manage, cause all the all the files were stored in one location. All the programs are installed in one location,
18:03
but all you're doing is providing a device to display that.
18:11
All right,
18:23
so in this example, you can see the server on the far left
18:27
with multiple clients talking back to it.
18:33
It's also a little more secure because the dad's not being stored. So someone actually got that thin client in their hand. They're not gonna be able to get anything off it. There's
18:41
all the important data is being stored on the server
