    In computer science, a system where two or more computations are executing "at the same time" (literally or effectively) is called a:

    Concurrent system

  • 2

    What is the primary difference sometimes reserved for "parallel systems" compared to "concurrent systems"?

    Parallel systems involve computations literally proceeding at the same time, often on different cores.

  • 3

    In POSIX Threads (Pthreads), the function typically called by a parent thread to create a new thread is

    pthread_create

  • 4

    The ______ method in Java is used to start the execution of a newly created thread.

    start()

  • 5

    In a multi-threaded process, all threads share the same program counter and stack.

    False

  • 6

    The number of possible execution orders in a concurrent program grows exponentially with program size.

    True

  • 7

    Making sure threads never have any variables in common is always the most practical solution to avoid race conditions in complex operating system components or multi-threaded server programs.

    False

  • 8

    Which of the following statements accurately describe a concurrent system? (Select all that apply)

    Two or more computations are executing, literally or effectively, "at the same time.", It can involve multiple threads sharing the same core by multitasking.

  • 9

    What is a "thread" in the context of operating systems? (Select all that apply)

    A specific sequence of instructions defined by some program or section of a program., Instruction sequences from one thread may run in parallel or be interleaved unpredictably with sequences from other threads., Every process has at least one thread.

  • 10

    When discussing "non-determinism" in concurrent programs, which of the following are true? (Select all that apply)

    Even simple concurrent programs can have many possible orders of execution., Different orders of execution may lead to different outcomes.
