• A counting semaphore was initialized to 10. Then 6 P (wait) operations and 4V (signal) operations were completed on this semaphore. The resulting value of the semaphore is                   
• Let S and Q be two semaphores initialized to 1, where P0 and P1 processes the following statements wait(S);wait(Q); ---; signal(S);signal(Q) and wait(Q); wait(S);---;signal(Q);signal(S); respectively. The above situation depicts a                .
• A semaphore is a shared integer variable                     .
• The                           operation similarly computes an element-wise reduction of vectors, but this time leaves the result scattered among the processes.
• A system has 3 processes sharing 4 resources. If each process needs a maximum of 2 units, then
