Hello. My name is Dustin, and welcome to virtual ization and operating systems.
00:06
We're going to go over client OS versus a server all West and some of the differences and uses between them. So both client operating systems and server operating systems have a lot in common, but they do have different uses.
00:22
So first up, we've got our client operating system, and this is an operating system that operates on typically on desktops, laptops and mobile devices like your cell phone or tablet
00:33
client. Operating systems of teen service is from a server operating system. So again, these run on client devices and typically quiet operating systems on Lee allow or, um, serve a single user at one time.
00:49
They are usually pretty simple to use. Anybody can use one. Um, and some examples include Android, Mac OS or the Windows OS.
01:00
So a server operating system
01:03
thes air operating systems that are designed to be used on a server they provide the service is to multiple clients, so they'll serve multiple clients across the network.
01:12
These typically run on server hardware, so it's like a server blade, but you can install server os is unlike an old desktop you've got laying around
01:23
the server West is Do serve multiple clients at the same time, and they're much more advanced than a client operating system. They've got a lot of features Then. If you've never used a serve, you may not be familiar with
01:37
a couple. Examples of some server operating systems are Red had Enterprise Lennox, Windows Server in various versions and Mac OS X Server.
01:49
There's a lot of differences between a client and a server, so client operating systems operate within desktops and various portable devices, while server operating systems are meant to be installed and used on a single server, Although it's not always necessary. Like I said, you can install a server operating system
02:08
on like an old desktop you've got laying around as long as it needs those hardware requirements
02:14
server operating systems can provide service is like active directory service is That's the user Names and Longs and Loggins DCP service is. They can actually send out I p addressing file storage and print sources to Client OS Is.
02:31
Client devices typically have less stringent hardware requirements, especially with storage, processing, power and memory servers do require a lot of that stuff, since they're serving a lot of purposes.
02:44
Only a single user can work on a client operating system at any one time as server operating system support multiple users.
02:53
Server operating systems also contain much more advanced features than client operating systems.
03:01
One of the most popular client and server OS is is actually the Windows operating system. It is sold by Microsoft and started in the early eighties with Windows one point. Oh, The current client version of the Windows operating system is Windows 10 and the current server version is Windows Server 2016.
03:24
So Windows Service's manage a wide variety of functions on your machine, including network connections, a sound user credentials and display
03:35
Without service is, your computer wouldn't work.
03:38
The surfaces are a core component of the Windows operating system, and they enable the creation in management of long running processes. They all typically run in the background and can run even after the user is logged off.
03:52
Unlike regular software that you need to click to open
03:57
or open via command line, window service is typically start without user intervention.
04:08
So what does it all mean?
04:10
We now know that without service is your Windows PC wouldn't work. Service is extremely powerful and run without any user and act user interaction. Because of this malware malicious software, Um likes toe to try and hijack service's or register itself. It's a service.
04:30
It wants to keep that persistence on your machine. If you know what service is air normal, it's much easier to recognize things that are not normal and may need to be cleaned up.
04:45
So how do you know what's running on your machine?
04:47
You can use the built in Windows Process Explorer and Windows machines, but it may not only show you exactly what's running. There are some service. Is that run hidden from this?
05:00
So one thing you can do is use this process. Hacker tool.
05:05
Um, if you are specifically looking for malware malware, it really likes the just stay on your machine. It doesn't want to leave. It wants to use your resource is so it tries to hide. Writing as a hidden service or masquerading sometimes is a normal service, whatever it can do to remain undetected.
05:25
And this is where that process actor tool comes in handy.
05:28
It's ah, free utility that is barely very similar to the common windows process explore, but it gives you a lot more options with the process. Hacker tool You're able to monitor all your system resource is debug software, and it will help you detect identify malware, which is extremely good.
05:46
Important in order to clean mouth were infections. If you don't know what the Mauer's doing,
05:51
you don't know what type it is. It's really hard to track down every trace and completely remove it.
06:00
Since this is such a powerful tool, we're not gonna get too far into the weeds with it.
