Q
Explain:
Concurrency vs Parallelism?
A
Concurrency is about modeling a solution to allow composition of independent processes which execute in the same time.
Parallelism is about simultanious execution or potentially related processes in a parallel way.
Concurrency is not parallelism, but it potentially enables parallelism.
