An RSS Feed is basically a link, where new entries in a blog/channel/whatever are published in a format that an RSS Reader understands. So if you put that link in your RSS Reader, i.e. subscribe to it, then your RSS Reader will save that feed and always show new posts/videos/whatever in that feed to you.
