| 6 | +A Parallel program doesn't mean to be concurrent. A program that needs to be run sequentially is hard to make parallelize. |
| 7 | +Concurrency is all about breaking the code into sub program that can potentially run at the same time and at the end produce same |
| 8 | +result as if it would run as single unit. So, we cannot parallelise a concurrent program. |
