CONCURRENCY
Concurrency is naturally divided into:
1) Instruction level concurrency,
2) Statement level concurrency (executing two or more statements simultaneously),
3) Program unit level concurrency(execute two or more subprogram units simultaneously) and
4) Program level concurrency (executing two or more programs simultaneously).
