5. Types of Fork Join Fork Join Fork join Any Fork Join none

6. Fork Join Here all processes will run concurrently. Fork join will not complete/execute until all processes completed.

7. Fork Join Any Here all processes will run concurrently. Fork join will complete/execute if any one of the processes gets completed.

8. Here all processes will run concurrently. Fork join none will complete/execute if any one of the processes gets started . Fork Join None

9. Wait Fork Wait fork ; In Fork join any by using wait fork, tool will make sure that all processes gets completed

10. Disable fork ; In this if any fork gets completed , then it will disable another fork Disable Fork
