Concurrency in Operating System:

The operating system or OS allows the users to manage and complete all required tasks properly while maintaining time and quality. However, in most cases, users have the requirements to perform more than one task at the same time. In order to provide a proper solution, the OS have to maintain more than one process simultaneously for the users. This process eventually allows the user to execute all of their required tasks within the proper time. This entire process maintained by the OS can be identified as Concurrency. This process also includes multiple executions, calculations, accessing multiple computers at the same time and running multiple applications on the same computer.

Challenges associated with managing concurrent processes:

1. The performance of the ongoing processes can easily be affected due to the occurrence of concurrency within the OS. A concurrent process allows the computer to access multiple applications at the same time. This entire complex situation can eventually degrade the quality of the execution processes.
2. Concurrent process also includes the access of multiple computers within the same network simultaneously despite of their locations. Maintenance of this process can affect the safety of the global data while sharing it through different computers.

Solutions associated with managing concurrent processes:

1. Maintaining the threads and their priority management will decrease the performance quality issues within this process.
2. Users will need to assign locks while maintaining the global data share execution in this process. The inclusion of a two-phase or 2PL locking system can increase the data safety feature in the concurrent process.
