# Discussion: Models of Concurrency
**Questions for think, pair, share:**

1. What is the difference between event-based concurrency and the thread-based models we've learned about so far?

2. Describe a scenario where event-based concurrency could be used instead of threads.

3. Why might you prefer to use event-based concurrency instead of threads in some situations?

*Start by thinking of answers on your own. I will let you know when to start discussion.*

2. In scenarios where you can use either threads or event-based concurrency, which do you prefer? Why?

*Start by thinking of answers on your own. I will let you know when to start discussion.*
