Can someone explain the exact definition of concurrency in simple terms? or What’s the real-world def

In simple terms, the definition of concurrency is about *logical* simultaneity, not physical. It’s like a single CPU core switching between threads super fast—tasks *seem* parallel but aren’t.

Parallelism requires multiple cores/workers.

Fun fact: In networking, concurrency might mean handling multiple requests, even if they’re processed one after another.
