There are four main timelines on Mastodon:

Home - Your default timeline, posts from people & tags & groups you follow

Explore/Trending - Shows most boosted recent posts, most used tags, most shared links

Local - Latest public posts from people on your server (also called Live Feeds: This Server)

Federated - Latest public posts visible to your server from across the Fediverse (also called Live Feeds: All)

More info about these on the timelines guide:
