3. Process competition for resources

Conflicts arises among the various concurrently executing processes when they are competing for the same resource.
    Let us consider a situation in which two or more processeswant to access a resource,. Each of these concurrently executing processes is unaware of the presence of other processes and the execution of the other process. Hence, the state of the resources used, remains unaffected.
    No information exchange occurs between the competing processes and the execution of one process causes a significant affect on the behavior of the other competing processes if two processes want to access a single resource then th os grants the resource access to only one process and let the other process to wait, as a result of which the blocked process may never get the resurce and terminates in an inappropriate manner.
