For each statement below, decide whether it is true or false (I point each) (1) A thread may share data and code space with its parent. e (2) A thread may share a program counter with its parent. (3) While DMA (Direct Memory Access) is taking place, processor is free to do other th ings Trus The processor is only involved at the beginning and end of the DMA transfer. 9) A forked process shares its parent's data space at all times. Falsan (5) Context switch means a process switching from a "blocked state" to "ready state". sa (6) Ifa procss uses up its allocated time slot, a timer interrupt occurs and the process is placed in a BLOCKED Queue. T (7) In Producer/Consumer problem access to shared buffer must be done in a critical section, but access to "empty" and "full" variables doesn't need to be done inside a critical section. r (8) If mutual exclusion is not enforced in accessing a critical section, a deadlock will occur. tal (9) An acceptable way for implementing mutual exclusion is to let users disable interrupts before entering a critical section and enable them after leaving the critical section. (10) If there is no mutual exclusion condition for any resource in the system, then there is no possibility for deadlock. True V. Multiple choice questions.
