What is a VPS?

[roald]

A virtual private server (VPS), also referred to as Virtual Dedicated Server or VDS is a method of partitioning a physical server computer into multiple servers such that each has the appearance and capabilities of running on its own dedicated machine. Each virtual server can run its own full-fledged operating system, and each server can be independently rebooted.
The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen a resurgence lately with the development of virtualization software and technologies for other architectures.
Virtual private server hosting

A growing number of companies offer virtual private server hosting, or virtual dedicated server hosting as an extension for Web hosting services. Some web hosting companies call a Virtual Private Server a Virtual Dedicated Server/Dynamic Dedicated Server or the other way around.
Managed Hosting

Tools are provided to monitor and control the machine.
Unmanaged Hosting

Typically only minimal services are provided, such as ssh console and reboot. Unmanaged VPS hosting is generally less expensive than managed VPS hosting.
Unmetered Hosting

Similar to unmanaged hosting but a fixed bitrate is offered so that it is not possible to exceed a monthly budget.

IMO, unmanaged VPS is intended for those users who can administrate the VPS using their technical knowledge.

A virtual private server (VPS) is a virtual machine sold as a service by an Internet hosting service. A VPS runs its own copy of an operating system, and customers have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS.

Good info is shared here, thanks.

Unlike on shared hosting, on a VPS you have full root and administrative access, you can install any software you want and what is also very important, you have dedicated only to your account server resources like CPU units and RAM. On the shared hosting these are spreaded between accounts on the server and if some gets overusage or sends spam, other accounts might experience a bad performance.
So if you're looking for a reliability and scalability, you'd go to a VPS hosting. You can get one from as low as EUR 7.99 /mo. with professional customer support.

A virtual private server is also known as virtual dedicated server (VDS). A virtual private server (VPS) is a virtual server that the user perceives as a dedicated/private server even though it is installed on a physical computer running multiple operating systems.
A single computer can have several VPSs, each one with its own operating system (OS) that runs the hosting software for a particular user. The hosting software for each VPS can include a Web server program, a File Transfer Protocol (FTP) program, a mail server program and specialized applications for activities such as e-commerce and blogging.

^ There're unmanaged, semi-managed and fully managed services available on VPS plans at good hosting providers, while unmanaged means, that end-user is fully responsible on fixing any problems (except with hardware node); Semi-managed service offers basic VPS management - OS install/reinstall, patches, updates, network and VPS monitoring and alerting, start/stop/reboot services and so on. Fully managed is like you have a normal hosting account, where you don't have to worry about server specific issues, but just use your VPS as an end-user, of course with much more privileged level.

VPS server is also called as VDS (Virtual Dedicated server) cause it provides complete control over the OS selection and applications on your server along with root access.

Virtual Private Servers are less-expensive alternatives to dedicated servers, while still allowing nearly the full server access of dedicated hosting.

for someone who want to install their own software but at low cost to maintain it.

VPS hosting is a Virtual Private Server, and is a virtualized server. A VPS hosting environment mimics a dedicated server within a shared hosting environment. It is technically both shared hosting and dedicated hosting.
