A process is an ‘active’ entity as opposed to program which is considered to be a ‘passive’ entity. Attributes held by …
CPU Scheduling In Operating System? CPU Scheduling CPU scheduling is a process which allows one process to use the CPU while the execution of another process is on hold(in waiting state) due to unavailability of any resource like I/O etc, thereby making full use of CPU. The aim of CPU scheduling is to make the …
Process Synchronization means sharing system resources by processes in a such a way that, Concurrent access to shared data is handled thereby minimizing the chance of inconsistent data. Maintaining data consistency demands mechanisms to ensure synchronized execution of cooperating processes. Process Synchronization was introduced to handle problems that arose while multiple process executions. Some of …

Classical Problem of Synchronization Problem of Synchronization Following are some of the classical problem faced while process synchronization in systems where cooperating processes are present. Bounded Buffer Problem This problem is generalised in terms of the Producer-Consumer problem. Solution to this problem is, creating two counting semaphores “full” and “empty” to keep track of the current number …
What is a Deadlock? Deadlock is a set of blocked processes, Deadlock holding a resource and waiting to acquire a resource held by another process. How to avoid Deadlocks Deadlock can be avoided by avoiding at least one of the four conditions, because all this four conditions are required simultaneously to cause deadlock. Mutual Exclusion Resources shared such …
