In your own words, explain what cloud gaming is.
```hint Trace one button press
Follow what happens between a player pressing a button and seeing the result on screen, and note where that path differs from playing on a console in the same room.

### Clarifying Questions
- Should the explanation suit a non-technical listener, or go into the streaming pipeline and where its delay comes from?
- Should I contrast it with related models, such as game subscriptions that still download games to the player's device?
- Is the interest in the technology only, or also in the business model and who the service is for?
### What a Strong Answer Covers
- A precise definition: the game runs and renders on remote servers, and the player's device only sends inputs and shows a video stream.
- The end-to-end pipeline (input, server simulation and rendering, encoding, network, decoding, display) and where latency builds up.
- Benefits for players and publishers, and the requirements and limits: bandwidth, latency, data caps, server cost and game licensing.
- How it differs from adjacent ideas such as streaming from your own console, download subscriptions and cloud saves.
- Examples of services and business models, with an honest read of where cloud gaming fits today.
### Follow-up Questions
- Which kinds of games suffer most when played through the cloud, and which work well? Why?
- As a PM for a cloud gaming service, what would you do for players on poor connections?
- Why is serving cloud gaming more expensive than streaming a film, and how does that shape pricing?
Overview: A technical concept question from a product manager interview at NVIDIA that asks the candidate to explain cloud gaming. It tests understanding of how games are rendered remotely and streamed as video, where latency and bandwidth limits come from, and the benefits, costs and business models behind the approach.
