Virtual private server (VPS) is a term used by
The terms virtual root server (VRS) and virtual dedicated server (VDS) are also used as synonyms of VPS. However, the latter also occasionally indicates that the server does not use burst/shared RAM through multiple machines and may use individual CPU cores. The term cloud server is also used to describe the same concept, normally where such systems can be setup and re-configured on the fly.

In a fully virtualized environment, the guest is presented with an emulated or virtualized set of hardware and is unaware that this hardware is not strictly physical. The hypervisor in this case must translate, map, and convert requests from the guest system into the appropriate resource requests on the host, resulting in significant overhead. Almost all systems can be virtualized using this method, as it requires no modification of the operating system, however a CPU supporting virtualization is required for most hypervisors that perform full virtualization.
In a paravirtualized environment, the guest is aware of the hypervisor and interfaces directly with the host system's resources, with the hypervisor implementing real-time access control and resource allocation. This results in near-native performance since the guest sees the same hardware as the host and can thus communicate with it natively.

As such, it is a common solution for operating systems which cannot be modified (for various reasons) to support paravirtualization.

A growing number of companies offer virtual private server hosting, or virtual dedicated server hosting as an extension for
Unmanaged hosting
The customer is left to administer their own server.
Unmetered hosting
This type of service is generally offered with no limit on the amount of data-transferred on a fixed bandwidth line. Usually, unmetered hosting is offered with 10 Mbit/s, 100 Mbit/s or 1000 Mbit/s (with some as high as 10Gbit/s). This means that the customer is theoretically able to use 3.33~ TB on 10 Mbit/s, 33~ TB on 100 Mbit/s and 333~ TB on a 1000 Mbit/s line per month (although in practice the values will be significantly less).

The term is used for emphasizing that the virtual machine, although running in software on the same physical computer as other customers' virtual machines, is in many respects functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer, and can be configured to run server software.The terms virtual root server (VRS) and virtual dedicated server (VDS) are also used as synonyms of VPS. However, the latter also occasionally indicates that the server does not use burst/shared RAM through multiple machines and may use individual CPU cores.

The concept behind server virtualization is a specific example of the same concepts that led to the development of

. Generally, client users tend to ask for computer resources in a "bursty" fashion, demanding fast-as-possible response to requests, but then entering long periods of no activity while they examine the results. During these idle periods, the computer's resources can be used to service requests from other clients. This model makes more efficient use of the computer's resources, reducing the time the system is idle, regardless of user patterns. It also allows the users to share resources, save files on a

shares access to the resources, but there is still a single machine being shared. In the virtual server model, the virtualization software instead provides the illusion of more than one computer, hard drive, printer, etc. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security as the individual virtual servers are isolated from each other. Each virtual server can run its own full-fledged

A VPS is a virtual computer put on a very good computer. When you buy one you pay monthly for it and it goes on a different person's computer in what's called a DATANCETRE. They have crazy fast computers with crazy fast internet (Usually). Usually running Windows or Linux server type operating systems. If you need to host a game server, or something that needs to be up 24/7 this will be your best option.

A VPS is a Virtual Private Server
It's pretty much a second computer that you buy / rent since you pay each month. This computer stays online 24/7 unless the hosting company has errors / downtime.
To access this ONLINE computer you use the built in software on Windows 7 called "Remote Desktop Connection"
Type that into Start Search
Then you input your VPS IP that you get given when buying it and it will open up your second computer in a window
You can then log in and like you would on your own computer, use XAMPP or IIS or any other server to host website pages and because this computer is designed so that other users can see the output on websites
You can run game servers on this
Hope this simple explanation helps more than the nub that posted a wiki page

If you bought one you'd press start, type in "mstsc" press enter, type in the VPS' IP, press enter, and type in the login information.How do i use it..
How do i use it..
- Open Remote Desktop Connection
- Copy and paste the IP your VPS provider have given you on e-mail/support ticket.
- After that, click 'Use another account'
- Type 'Administrator' usually and write the random password generated.
- A separate window will pop-up, and that's your VPS, install things and use it as if it's your own computer.

You can download stuff on the vps right? because u said it's like a 2nd computer.

You can do things like what you do on a computer, except that it has a better internet speed and they are specialized to run server-side applications like IIS or game emulators. Also, you need to adjust security settings in order to download.

How would you adjust to settings so u can download?

I don't know how to do that lol tell me?I mean your Internet Explorer settings, it's set to high by default so you have to get Google Chrome... and still adjust security settings by enabling Active scripting.
