Virtual Private Server vs. Dedicated Hosting
web hosting
A Virtual Private Server is where you are running a virtualised OS sitting on top of shared hardware - so you're probably sharing the physical machine with a number of other servers.Dedicated Hosting is where you are renting the entire server, and get all its resources to yourself.That's why VPS is usually a lot cheaper than Dedicated, because the host can effectively sell one server 8 or more times, taking up much less rack space, etc, for the same price as one dedicated server.
