Example for deadlocks:
Consider the following situation: Suppose that two processes (A and B) are running on the same machine, and both processes require the use of the local printer and tape drive. Process A may have been granted access to the machine's printer but be waiting for the tape drive, while process B has access to the tape drive but is waiting for the printer. Such a condition is known as deadlock. Since both processes hold a resource the other process needs, the processes will wait indefinitely for the resources to be released and neither will finish executing.
