Concurrency (并发)
- A way to run multiple Thread at the same time, instead of running one thread after another thread is done . Thus, improving the overall performance
- Can be achieved with multiple Core or Context Switch when there is only one Core
- Used to maximise the use of resources on hand and handle multiple requests or events
Parallelism (并行性)
- A subset of Concurrency (并发), Thread run on its own Core, so it is concurrency running on multiple resources
