If there are writers waiting to alter the resource and new readers arrive all the time, the writers will never be allowed access as long as there is at least one active reader. Give emphasis to authors; readers may go hungry here. Starvation can also occur if all the readers are waiting for their turn to use the resource but none of them has yet. In this case, too, no writer can make any changes to the resource because they all want it to be as fresh as possible when they read it. This example shows that starvation can also happen when everyone wants the same thing at the same time. Finally, starvation can also occur if some readers are waiting for their turn while others are not. For example, let's say that there are 10 readers and 5 writers. Readers 1 through 5 are waiting for their turn, while readers 6 through 10 are not. If all the writers try to give priority to readers 1 through 5 first, then readers 6 through 10 will never get their chance to use the resource! In conclusion, starvation can occur whenever there are multiple readers or writers who want to use or alter a shared resource simultaneously.
