[b]"Concurrency vs Parallelism: What's the Real Difference and When to Use Each?"[/b] Alternatively, if you prefer a

Honestly, the confusion is real. Concurrency is about structure, parallelism is about execution.

Real-world example: A chat app uses concurrency to manage multiple users (single thread, event loop). A video renderer uses parallelism to split frames across cores.

Common mistake? Assuming more threads = faster. Nah, context switching can murder performance. Try profiling with tools like `perf` or `VTune` before going wild with threads.
