A servar is a computer on a network that provides services to other computers connected to the same network. Windows, Linux, and Mac servers.
What is a Servar?
You know Windows 2008 server is a servar but that is not the only thing that can be a servar.
A file servar is a computer on the network that has files in it that other people can get to a print.
The servar on the network is a computer with a printer attached that can share out that printer with other computers on the network.
So if somebody presses print on one computer and it will print out on another computer.
A web servar is simply a computer with special software installed on it that allows that computer to present websites to people.
So all the servers are some computers on the network that provides services to other computers.
Now, this might be Windows 2008 servar, Windows 2003 server, Ubuntu server, Red Hat Linux Enterprise Server Edition.
It can also be a Windows XP home edition computer that simply has a shared folder that everybody can access and grab files.
So one of the big things that I want to get through your head is that all the servar is a computer on the network that provides services to other computers on the network.
Many people waste a lot of their own money and a lot of other people’s money because when they go oh I need a file servar.
Let’s say they have a little office. And they have 5 people in that office.
They go oh I need a file server. Well, they run out and they spend $4000 for an enterprise-class Windows 2008 server.
And they can now share out the files with everybody in the office.
And they go WOW bonus I now have a file server.
Well, they did not need a full Windows 2008 server to share out a few files on the network.
They could have used lie I say, Windows XP home edition to share out files in the network and it would have been a lot less expensive.
So the main thing when we define a servar is that a server computer doesn’t have to have a servar in the name of the operating system.
All the computers can be a server that has to provide services to other computers on the network.
So now that we have defined what a server is so a server is something like a computer on the network that provides services to clients on a network.
We have to kind of differentiate between servers and servers.
What do I mean by that?
Well in the real world you basically have two different types of servers.
You have the Little File Server sitting in an office with five people.
That people either backup files to or they get something off of every once in a while.
It is a server useful for people who share information but if the servar crashes or something goes nobody is really going to lose their mind.
Then you have Real Servers. Those are computers that have to be on 24 hours a day seven days a week. If they stop functioning ever for any reason everything just goes to absolute hell.
They rarely even get rebooted. They get rebooted maybe once a month or more likely once every two or three months.
These things have to be rock-solid stable. If anything happens they have to be able to survive small problems.
So if there is a small problem in the operating system or the hardware they have to be able to survive that and keep going. Because if something fails well then the entire business just goes away.
So we have defined servar as providing services for clients on the network.
We do have two very different types of servars.
You have the server like I say that deals with five people in an office it has a printer connected to it. It has some shared files you know again if it dies nobody is going to lose their files.
Other servers have to be up 24 hours a day seven days a week. When most people talk about servers these are the types of servers that they are going to be talking about.
They are going to be talking about rock-solid pieces of equipment that basically should never fail.
So just keep that in mind there are two different types of servers in the world and we’re going to go into that in these next two sections
When we talk about the servar operating systems and then servar hardware
So let’s take a moment to talk about servar operating systems.
As we said before the little Windows XP home computer can be a server but the issue with that little XP home computer is that, it is not designed to be on 24 hours a day and seven days a week to never be rebooted.
You can either do some more processing or play video games on.
Well, Microsoft and all the other companies out also create server operating systems.
Server operating systems are more robust more stable and generally more secure than desktop operating systems.
So if you are thinking why don’t we use that Windows XP home computer because that is going to be a lot less expensive than buying a full-fledged Windows 2008 servar.
It really depends on what you need that server for.
If you need to share files with 5 or 10 people in an office, a little Windows XP computer would be fine for you.
Windows 2008 servers or any servers whether they are Linux or Mac OS actually have a full servar.
They are made to be much more robust and to deal with many more incoming connections than the little home desktop computers.
Imagine and realize that real server operating systems like if you are dealing with Windows 2008 server and you are using it for what is called an Active Directory servar.
So people actually log into it and they gain resources to the network. One single Windows 2008 server can support up to 10000 users.
So that server software is much more robust and can deal with far more users and far more issues than the little desktop operating system.
Well so the reason people use the server operating systems versus the desktop operating systems is again they can scale up.
They can deal with far more users than a desktop computer.
One of the things you have to realize when you are dealing with servar operating systems is a lot of times they can seem much more complicated than desktop computers.
Because they actually don’t come with as many of the nice little friendly user tools that desktop computers come with.
Since you are new with servers something to think about is that every time you put a piece of software or put a piece of functionality onto a computer into the operating system.
Not only do you get that extra functionality but you also get possible extra flaws bugs and defects that hackers can use to compromise that system.
So when you install flash on your computer you like it because you can watch videos but that flash actually has security holes that hackers can use to take over the computer.
So when the vendors create server operating systems they don’t put in as many of those nice little features into the server operating systems.
Because they want to make the server operating systems more secure.
So if you are dealing with a Windows 2000 servar when you go into it you are going to notice that it is much more difficult to get around and administer that servar than it is a normal Windows desktop computer.
Because there is not as many nice fancy little flashy wizards and easy to do stuff
If you use Linux like if you decide to use a bun to Linux as a serum you’ll notice if you download and install the desktop version of Ubuntu Linux you get a nice little graphical interface.
You can go in you can left-click you can right-click and you can do all the stuff that you think of when you use a computer.
If you download the server software after it reboots you are going to be seeing something that looks like a DOS prompt.
And there is just gonna be a little cursor that is blinking at you. And it will only do whatever you type into it to tell it to do.
So why they do that is because all those fancy little apps that make the server easier to use also create security holes.
So if you want a very secure Linux webserver you don’t want all the graphical stuff.
You don’t want Firefox installed. You don’t even want the GUI.
You don’t want cursors and buttons and all that. You just want that little dos prompt so you can type in and tell it exactly what you want it to do.
