@abhishek I think you should have made your introduction post independent instead of replying to mine. X3
But anyways, the Fediverse is basically an ensemble of interconnected servers. Mastodon is part of it. ^^
Imagine being able to subscribe to a YouTuber from Twitter. You can do that with Peertube and Mastodon.
So the cool thing about Mastodon is that it isn't just a network on its own. The developers implemented support for ActivityPub, so anyone from instance A can talk to someone from instance B.
That also works with other services like Frendica (FOSS Facebook): as they implement the same standard, someone from Frendica can like, favourite or boost a post from a Mastodon user.
And that's the beauty of federation. It isn't just one service. It's a collection of services all talking to each other. Anyone can start up a Mastodon, Plemora (lightweight Mastodon) or Frendica instance on their servers.
Compare this to something like Facebook. Someone from Facebook can't interact with someone on Twitter. When talking about those platforms, you will commonly hear the phrase 'walled garden'.
Hope this helped!
