machine server vs. dedicated server

[Stoddard]

Recently I came across two terms: "virtual machine server" and "virtual dedicated server." Are these 2 different things, or just 2 different terms for the same thing?

A virtual private server (VPS), also called a virtual dedicated server (VDS), is a virtual server that appears to the user as a dedicated server but is actually installed on a computer serving multiple Web sites. A single computer can have several VPSs, each one with its own operating system

The two terms means the same thing. VPS (Virtual Private Server) is the current hosting industry term for a Virtual Server.

Virtual Machine Server is an older term when virtualization was first starting, but still means the same thing.
