Principles of Concurrency : Both interleaved and overlapped processes can be viewed as examples of concurrent processes, they both present the same problems. The term real and virtual concurrency in concurrent processing: Multiprogramming Environment : In multiprogramming environment, there are multiple tasks shared by one processor. extent: • sharing global resources safely is difficult; • optimal allocation of resources is difficult; • locating programming errors can be difficult, because the In an operating system, this happens when there are several process threads running in parallel.

CONCURRENT PROCESS:-When multiple process having there overlapped execution time , then these process is known as concurrent process. The relative speed of execution cannot be predicted.

CONCURRENCY • It happens in the operating system when there are several process threads running in parallel. Operating System Concerns Design and management issues raised by the existence of concurrency: The OS must: be able to keep track of various processes allocate and de-allocate resources for each active process protect the data and physical resources of each process against interference by other processes may run at different speeds, but again this problem is mirrored in concurrency is the interleaving of processes in time to give the appearance of simultaneous execution.
