I'm new to hosting, and I know what shared hosting is (when your site is hosted on a server, where other sites are hosted), and I have a pretty good idea of what VPS means (your site is hosted on your own server.). What are the advantages/disadvantages of using VPS instead of Shared. Do you need a lot more knowledge in order to run the server. Do you have to provide your own security for the server. I know I'm a newb to hosting, but any help/suggestions/comments would be appreciated!
