What are some examples of concurrency in programming?

Concurrency in programming refers to the ability to run multiple tasks simultaneously. Examples include multi-threading, asynchronous programming, and parallel processing.

Can you explain multi-threading with an example?

Sure! Multi-threading allows multiple threads to execute concurrently. For instance, a web server can handle multiple requests at the same time using different threads.

What about asynchronous programming?

Asynchronous programming allows tasks to run independently without blocking the main thread. For example, in JavaScript, you can use promises and async/await to handle operations like API calls without freezing the UI.

How does parallel processing differ from concurrency?

Parallel processing involves executing multiple tasks simultaneously on different processors, while concurrency is about managing multiple tasks at once, which may not necessarily run at the same time.
