Welcome back to Cyberia, I tease. My name's just Lingle say, well, going over Module five, which is virtual ization set up as an overview, we'll cover hyper visors, virtualized host and virtual machines on happen visors. They're two different types of hyper visors. There's type one, and type two
proprietary open source will also recovering them. And then we're also going to get into the consumer versus the enterprise how they're going to be using socialization in the network.
Type one versus type, too.
as a type of V M that you load onto a bare metal machine. This is where you have the core loaded, which is basically a command prompt, and then you have via mes loaded inside of that core.
The purpose behind this it's that we don't have external resource is taking up your machine.
Type two, on the other hand, is where you have an operating system loaded, and then you have the arms loaded into that. An example of that would be the somewhere, or maybe hyper visor.
Type two uses more. Resource is
with time, too. You have the operating system running, which is using its resource is and then you have a program running using resource is, and then you had the PM's running, which you're using. Resource is, whereas the other one, you have the core loaded
and the core isn't using. Hardly any resource is. And then you have hyper visor, which is just the command line. You're not having to utilize the gooey functions,
and then you have the actual
machines running the video machines running. On top of that, those are what's using. The majority of your resource is
Proprietary is the term used to describe
a certain device or a certain
software working with the same company.
For instance, Mac Mac is a big user of proprietary.
Their cables work with Mac products. The the iPhone works with the Mac better than the worst of Windows. Have you had to have a specific cable to perform the functions?
Another example of proprietary is where the source code is not offered to you. For instance, Microsoft Word
Microsoft Word is an executed ble,
but the source code isn't given to people, and sometimes with proprietary, you have license ings or you have subscriptions that are associated with them. On the other hand, you have open source and open source is where you're given this information freely, where you don't have to buy a specific cable to work with a specific device.
For example, the USB micro is a connector that was used in a lot of
mobile devices, phones and tablets. However, most vendors have moved away from that and have their own top of cable. But
if you have that open source, then you're able to use them with any computer and with any device you don't have to have their specific cable to be able to use that you can buy the cable from anywhere. Another thing with open source is that the source code is available to you.
Firefox Firefox is available to you, and anybody can take it and modify it and use it as needed. We're talking about VM. You have consumer and enterprise consumers. Use me. I was a little bit different than an enterprise would.
For example, a consumer would not have as many operating systems loaded on their VM. They might have windows and then other versions of windows loaded onto it, whereas an enterprise would have unit floated as a V M as the core and then have Windows Server 2003
Window Service 2000. They are, too, or some other type of program running on it.
Another thing with the consumer is it's not meant to support many users.
Most people that have Diem's at home. They run that instance for testing.
They will take a program and install it onto a V M, see how the program operates and how it reacts. And then they will delete that program were delete that VM versus installing it on the computer. When an enterprise uses VMS, they will actually give their users of the M toe work with instead of an actual computer
a lot of time whenever
talking about consumers. They're using Type two, whereas Enterprise is primarily used. Type one.
Next, we won't talk about virtualized hosting virtuous hosting. We have hardware assisted bios, CPU, memory and Nick. The purpose behind hire a system system virtualization is to improve the user's performance Hyper V and van. Where are the most common programs associated with
personalization? It utilizes the actual hardware that's inside of the computer to make the VM run better. And with hardware assisted virtual ization, it gives the user
use. Other time, they're able to see their CPU uses where they're able to see how many cores air using or how much memory they're utilizing. This way they can manage their information better,
but they could manage. Their resource is better. Bios. Bio Stands for Basic Input Output System The purpose behind BIOS is for that away. It's able to find all the hardware that your computers using
and put it in a clean sheet so that away your computers ever to utilize those functions to their full extent. Most time bios is a preloaded software from the manufacturer, and it saved on chips that are attached inside the motherboard. If you've ever heard the term
flushing the BIOS, that means you're deleting your BIOS and installing a new BIOS.
Bios is also firmware, which we'll talk about later on, too.
The boss is used for a quick save of all the devices and all the pre feels that are on your computer, so this way it doesn't have to rediscover them. Every time CPU CPU stands for Central Processing Unit
It is the brain of the computer,
and essentially one core CPU means you're able to run one process at a time, but if you have a dual core, that means you're able to run to quad Core is four
run up to 12 course. However, for the consumer, most time they use either a 246 or eight most of time.
12 and A are used with enterprises,
and most of time they're used on a server.
Just because you have
many course doesn't actually mean that you have a strong computer. That just means that you're able to run many processes at the same time.
With these 12 core processes, they might be
Where's your computer at home running at four. Get a four course is running at about four gigahertz,
so you're able to perform the functions more. But you're not ableto to perform as many functions as a server. Camp with CPS is very important to remember that each CPU needs a court. You can share cores with sea views, but if you're a sharing course than it will cause your VMS, Iran slow. So utilizing that
to its full extent is very important
