How is a VPS different than shared hosting?

A VPS eliminates the restrictions of shared hosting by giving you the power and flexibility of a dedicated server with your own set of services and customizable disk space. Shared hosting is limited in comparison because its users do not have administrative access and software configurations cannot be customized, despite the fact that physical resources are also multiplexed. With a VPS, you can control your own unique file system and CGI-BIN, disk space, system resources, bandwidth and memory allotments.
