Yes? Basically half of them? Some people put federation in decentralised group, some say only distributed is decentralised.

In short: centralised = 1 owner/operator, federated = many semi-autonomous operators to choose from, decentralised/distributed = everyone's an operator on the same level.

With DNS you still have groups of operators who can tell you what to do and they have the main agencies on top of that. I subscribe to the "it's not really decentralised" view.

Alternatively, do a quick search for "decentralised vs federated" yourself. People here don't owe you basic explanations.

It's not that I am dumb and I am asking for help with info. I'm questioning the existence of this, there is no reliable source because these are not standard terms in any discipline.

It's not that you are not giving me source because your time is valuable and I'm dumb. It's because there is no source and these concepts don't have any standard rigorous definition.

Google gives me trash. These are trash concepts, nothing written by academics or professionals or standard textbooks, or proceedings of magazines or publications.

Just blogs and cryptonerds (with different definitions).
