"Concurrency is when two or more tasks can start, run, and complete in
overlapping time periods. It doesn't necessarily mean they'll ever both be
running at the same instant. Eg. multitasking on a single-core machine.

Parallelism is when tasks literally run at the same time, eg. on a multicore
processor." -- Stack Overflow
