A memory leak is:

Programs request Operating Systems for some Memory (ALLOC) for its own use which they later on FREE up. Sometimes Programs do not free up the memory that was given to them by the OS, which means that every time they run the 'forget' to give back some of their memory to the OS. Over several executions this 'drain' in memory causes a LEAK and OS runs out of free memory.
