A system must transfer large amounts of data frequently between processes. Compare message passing with shared memory for this use case, and identify an important coordination requirement for the approach that uses a shared region.

True
- B
False

A running process has more work to do, but the scheduler ends its time slice so another process can use the CPU. Which state should the first process enter?
- A
Blocked, because preemption means the process is waiting for an event.
- B
Ready, because it can run again but must wait for CPU time.
- C
Terminated, because its time slice has ended.
- D
New, because the scheduler must create it again.

A child process calls an exec function after being created with fork(). Which outcome describes what happens to the child?
- A
The parent process is terminated and replaced by the new program.
- B
A new PID is assigned to the child, while its original program keeps running.
- C
The process continues, but its program image is replaced by the new program.
- D
The new program is started as a thread in the parent process.

A shell must connect one program's output directly to another program's input as a stream of bytes. Which IPC mechanism best fits this design?
- A
A pipe, which carries a byte stream from a write end to a read end.
- B
A signal, which transfers the producer's complete output as data.
- C
A process identifier, which carries output between programs.
- D
A semaphore, which stores the producer's output for the consumer.
