How does the ELO rating system work in competitive gaming tournaments?

Can someone break down how the ELO rating system is calculated and applied in tournament settings? I'm curious about the underlying formula, how win‑loss records influence a player's score, and what factors cause large rating jumps. Also, how does the system handle new entrants and inactive players? Any visual examples or common pitfalls to watch out for would be helpful. What’s your experience with it?
