Is "Virtual Dedicated Server" a correct name?

I've been searching for differences between servers and came accross VPS and VDSs. Which are accordingly Virtual Private Server and Virtual Dedicated Server. For example in GeeksForgeeks they say that they use different virtualization techniques. Namely VPSs use OS lever virtualization and VDSs use "paravirtualization".

As my logic says to me Dedicated Server must mean a separate server machine dedicated to me. So any virtualization applied to this server breaks the rule of "dedication". So if this is the case Virtualization on a server must make it "Virtual Private Server". I think this name is more applicable to a virtualized server.

So. Why there are two different things such as VPS and VDS. I am very confused.

P.S. In this link Google says that there are 3 kinds of hosting: Shared, VPS, and Dedicated (without the word "virtual"). So can I come a conclusion that VDSs are actually a misnaming for VPSs?

Most providers will give you anything you want if dedicated. The business model for non-dedicated is if you can jam 120 virtuals on a server using paravirtualization that is more profitable that 100 virtuals. The reality is customers don't have a way of measuring this or assigning an SLA to it, so it isn't meaningful. Also the most popular providers are selling you a service that meets a specification. They aren't selling you "paravirtualization". Nearly all of these are throttled so that any and all technology, dedicated/non-dedicated, paravirtualized/non will provide the same performance.

The terms have nothing strictly to do with with the type of hypervisor used, though you may see patterns.

The only real difference is that with a VPS you are highly likely to be running on hardware shared with other users, whereas with a VDS you will have the full resources of the server, minus any hypervisor - if used - overhead.

The actual type of hypervisor plays no real part in this.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
